Paul, the bed should be the same from 73-79 (someone correct me if I'm
wrong on this). However, it is possible that an earlier bed could have
been put on but it wouldn't be a fun job as the frame rails are off by
about an inch on each side. What is the width of your taillights at the
widest point? If its wider than 2 7/8" than you have the correct bed,
if its 2 7/8" you have a 67-72 bed. Also, keep in mind that there's more
than one bed length. The fleet site bed came several lengths but for
simplicity sake I just call them long, standard and short.

I'm fixing to put a 460 and c6 out of a car into my bronco, am I going to
have this shifter problem. Second, am I going to have a problem with the
output shaft?


Shifter Problem = NO
Output Shaft Problem = YES

If you are converting your 78 4 speed Bronco to the 460 C-6 setup you will
need an automatic style steering column with the transmission shift lever.
Go all the way and find a tilt column. I bought mine in excellent condition
for $35. To attach the C-6 to the married type NP-205 transfer case you will
need the married type rear C-6 tail shaft and the internal rear output shaft.
You can either locate a complete C-6 transmission with the correct 351-400M,
460 bolt pattern or you can buy any pattern of a core and have the rear end
of it installed to the C-6 you already have. You should also be aware that
there are two different lengths of these adapter/shafts setups. To decide
which one you need simply measure the length of your 435 transmission and
bellhousing. Measure the C-6 from the front of the case to the point the
rear output bolts on. The difference is the length of adapter you need.

I am pretty sure that you will need the short adapter. My C-6 with the short
adapter is sitting in the garage, let me know if you need to know the length
of it. I believe that if you get under you bronco and look at the frame you
will find 2 sets of holes for mounting the transfer case to either the long
adapter or the short one. The problem is if you get the wrong adapter length
you will need to make or buy 2 new drive lines.

All of the old 77 1/2 to 79 adapters are made out of steel. For my setup I
bought an adapter that was cast aluminum. I think that it is used to connect
a C-6 to the NP 208 case on and early eighties Bronco, but I am not certain
about that part. If you are unsure what you need simply buy a gasket for the
connection between the C-6 and the 205 and you will have an instant parts
identifier.

Hi Gang,

I know this might have been talked about before so, please forgive me. I
want to convert my front brakes(drums) to disc brakes. I've heard to go to
the boneyard and get parts from a vehicle that has them. If this is the
case, what year truck would I need to look for? What parts do I need? Are
there any other ways of getting the parts? What is the cost going to be? Is
it worth the hassel? Thanks in advance.

I'm really rusty now but seems like the shaft can be replaced without
tearing the whole thing down but one person said otherwise so I'm not
sure. I did it a long time ago. The linkage isn't really a
problem, it just requires a little adjustment to the bar and flip
flop of the lever on the transmission. The key is to make sure it's
in park when the shifter on the column says it is which generally
means all the way forward unless your linkage uses a bell crank which
reverses the direction. I think I had to weld in a 4" piece of rod
on mine to get it all to line up and reverse the lever and that was
it. (that was in a van tho)

What engine do you have in there now? What transmission? If you
already have a c-6 in there, just bolt it up to the 460, otherwise
you will have to find the short tail housing, output shaft and
transfer case adapter to make it work.

George: In a previous thread a gentleman asked about the car C6 in a
4wd application and I believe the answer was the output shaft was
different in some ways. If you need a trans, I have a truck C6 in my
garage as well as a NP203 xfer case.

What I can tell you from your VIN is this:

F25F-250 2WD
M390 4V V8
CAssembled at Chester, PA
W45194My book doesn't show production months for this model year but
"W" is fairly early because the serial numbers for 1975 are
V20001 - X40000.

You can get a build sheet for this vehicle by contacting Ford Customer
Assistance Center. They only do a certain range of years but I think yours
is covered. Their address (I think, somebody correct me if this is wrong)
is cacinfo ford.com.

Subject: Oil guage reading low
Message-Id:
Content-Type: text/plain; charset="us-ascii"

I saw a thread in one of the archives about an oil guage reading low. I
had a similar experience with my 76. It turned out to be the voltage
regulator that supplies current to the oil pressure, water temperature,
and gas guages. It is a mechanical style regulator that works by
interrupting current to the guages.

To check it you can turn the key on (ACC or ON) and put a volt meter
between the wire for the oil pressure or the water temperature guages
and ground. You should see a fluctuating voltage between 8 to 12 volts.
When mine faild it output a steady voltage of 5 to 6 volts. The low
voltage caused all three guages to read low. (Believe me its a bad
feeling to look down and see the oil pressure on the L). The regulator
is located on the back of the instrument cluster. It is silver about 1
inch long .5 inch wide and has a connection similar to a 9 volt battery.
Cost me about $12.00 and it was a snap to replace.

By the way, one way to check the sending unit would be to check its
resistance with the engine off (should be a high resistance) then start
the motor. The resistance should drop as the pressure comes up. (about
half the resistance when the motor is off). Sorry I don't have exact
values but look for the change in resistance.

Hope this helps

Shell says it's the best thing since sliced bread...Fuel additives at
the pump...just push the button for protection, cleaning or
performance 1,2,3...

#1 (protection) gives you corrosion protection, reduces gum, varnish,
wear, water in tank and safeguards performance

#2 (cleaning) gives you polyibobutylene amine with a synthetic
synergizer (what the hell is a synergizer) it reduces deposits,
cleans injectors, valves and reduces emissions

#3 (performance) formulated with a patented PEP molecule to improve
city and country driving, towing, grade driving. It restores power,
acceleration, stops knock and pinging and reduces sluggisness

WOW ! and it's right at the pump...
Somewhere in the background I hear someone saying "Trust me".


Marketed by Additech Inc of Houston Texas 1-888-additech

O.K., who knows what it is, if it works or are we really the ones
getting cleaned.

Your comments please.

Subject: vacuum gauge meaning
Message-Id:
Content-Type: text/plain; charset="us-ascii"

It has been awhile since i have had a vacuum gauge on a vehicle, and now i
forget what the readings mean. more specifically, if running at wide open
throttle against a constant load, is it better to show no vacuum or high
vacuum. it seems to me that there should be no, or very little vacuum under
these conditions unless there is a lot of restriction in the intake, heads,
carb combination. if these parts are flowing freely, and efficiently, low
vacuum is the result? at idle, i show 8 psi about, and 10-12 at 1000 rpm,
increasing at steady load - throttle conditions, but dropping to zero when i
smash the loud pedal.

does anyone agree/disagree with my idea about what should happen under WOT
and constant load? i havn't tried it yet, but will friday night.

if it shows no vacuum, i think a bigger cam will give more power, but if it
shows that there is vacuum, i think that my heads,intake,carb,etc. is too
restrictive for a larger cam. any thoughts out there in ford land?

BTW, this is a FORD 460, blue thunder 2 plane intake, holley, stock 73
heads(almost stock!), L&L fenderwell headers, MSD ignition from plug to
battery with computer timing control, TRW pistons, .030 over, CJ rods, stock....
