How different are the frames between these two body styles? How far off would cab mounts and core support mounts be if you were to take a 67-72 body on to a 73-79 frame. Thanks in advance.

 

Is It is a direct bolt up close enough for you? The difference is behind the rear cab mount. There is 4 inches added to the chassis there.

Im not quite understanding what you mean...Is the frame longer? Does the rear cab mount need moved? Do explain. And thanks!!!

 

Your question:
How far off would cab mounts and core support mounts be if you were to take a 67-72 body on to a 73-79 frame.

The answer:
It is a direct bolt up.

Further comment:
The difference is behind the rear cab mount. There is 4 inches added to the chassis there.

Meaning that behind the cab there is 4" added to the chassis length, that has nothing to do with the cab and front clip. The front of the chassis are the same from 65 to 79. A 65 cab and front clip is a direct bolt up on a 79 chassis and vice versa.

ok ok i see i was confused by your statement. So (from the cab- back) the frame is longer...Is this on the 67-72 trucks or the 73-79 trucks? Ok here's what Im doing you tell where the discrepency is..... I have a 71 F100 long bed reg cab 2wd I am putting that body on my 79 F350 4x4 reg long bed frame/chassis. Does that make sense?

 

Go for it.

I have the same type project going. I plan on putting a 72 F100 3-on-a-tree long bed 2wd cab & front clip on a 77 F250 NP435 4x4. The 77 cab has cancer real bad and the 72 is in good shape for the 35 years old.

Good Luck, Scottie

 

jow, I'm still not following you. Does this mean if you take a front clip, cab and bed from a 67-72 and put it on the newer frame, there'll be a 4" gap between the cab and bed, or that the frame will stick out 4" past the bed?

 

qman, Ford added 4" to the cab starting in 73. Look in one at the floor pan, it is easy to see, welded to the end of the pan. It was added so that the addition was added to the cab space but did not change the mount points. 65-79 2wd all the same.

FordboyPete says that you can fudge the 4 inches out in an install. I have not done one yet, but I would like to. I have contended that you might have to bob off the ends of the rails. You will also have to adjust the mount points.

Hope this helps a little.

There is only +2" difference in the wheelbases, irregardless of the +4" in the cab floor. All you gotta fudge with a 4X2 upgrade is + 2 inches in wheel base difference.
There is also a difference in CA frame width (the rear frame, after the cab) so when John says you have to remount the bed, that's when you "fudge" extra length away.

There is no 4" gap between the cab & bed if you do it this way.

So here's my situation. Taking a 70 F100 (2wd 4spd)Body moving it to a 79 1 ton 4x4 frame. If i have read correctly the cab and coresupport bolt right up.... I can make the bed work that is no biggie. But no major issue with cab/front clip swap, right?!?!

 

It depends if both have the same front suspension or not. If one has leaf & the other has front coils & radius bars, answer I would give is NO they won't just drop on, fit & bolt up. There are differences between both 4X4 and 4x4 and with spring types also.
The frame configurations are different between leaf & coil spring front suspension.
Having said that, you can make it work with engineering, alterations, effort resources & time, all something I avoid doing myself. I have done a few 2wd upgrades however &
they are as represented above by both of us.

We were 5 posts onto this thread B4 the topic of 4X4 v 4X2 came up. It's why I so specifically stated 4X2 when I jumped in here. In defference to our fearless moderator, that fact [ 4X2s as a drop on, bolt up] is what he was talking about too.

Ok well heellfire if there's a will there's a way....I'll give her a shot a take pics and let everyone know how it goes.... Ill be sure to keep you up to date, but don't expect answers too soon, because my goal is to be done by July 07. (not soon :P)

 

heck ive driven a truck with no brakelights or turnsignals over 700 miles.....how bad can this be

 

67-72 vs 73-79 ??

As far as looks... it's no contest!

67-72 Ford pickup is the best looking pickup ever made.

Alvin in AZ ('75 F150 special ordered it even)
ps- don't tell 'em over on the 73-79 forum I said that ok?
