Hi again,

Trying to find a bit of info regarding the wheel stud patterns on a 1968 F350. At least that is what we have come to be reasonably sure of what it is. The SWB (135 inchW.B) in 2WD configuration. Mine has the 6 (SIX) stud pattern, running 15" single rims, which may or may not have been added after. The rear Dana 60 also has the six stud pattern, the full floating axle end cap has 8 (eight) studs bolting the flange on. Having a lively debate here on an Australian F truck forum, where some are saying that in that era, F100 ran the 5 stud pattern rim, interchangeable with Inter and Jeep. They then go on and say that both the F250 as well as the F350, went to an eight (8) stud wheel rim. I even went out and took photo's to post, if ever I work out just how to do so. Because of a total lack of tags, stickers, comp plates etc, the only way we could place it is the "Bumpside" panels as well as the grille. Can't go by engine number as it had a reco with it's own stamped number in 1992, but that has since been identified as most likely the 240 Big Six. That's not the problem. I am only going on what I take to be my own knowledge, know how to identify the Dana rear end, likewise the tranny (NP 435). Front end , to me, is similar to a reverse Elliot drop beam with coil springs and a trailing arm either side which ends at the chassis almost level with the firewall.

I think that some of these guys on our local forum, may have either misread what I had written, or are talking a different era, because they are talking about leaf spring front ends, I thought that was only on that era's 4WD. I too may have confused the issue a bit when I asked about Dana 44 front ends fitted to the Ford trucks in a 6 (six) bolt pattern? But maybe the Dana 44 was ONLY fitted to the F100 4X4? Possibly the larger F250/F350 used a different open knuckle front end again??

Would appreciate a bit of a heads up on this. Cheers, Dave 64

 

Hi All,

Just as an added thought, trying to pinpoint the apparent difference in wheel stud count, I found a reference to a "Mercury F350" Canadian build which shows the wheel studs quite clearly as SIX (6) stud.

Is it possible/probable that Ford Broadmeadows were simply using up old stocks of previous years components? I know from experience that Jeep did it quite often, especially in early days (60's-70's). If so, it COULD explain just why my vehicle (supposed to be a 1968 F350) has the apparently odd wheel sud count for that year. Or, maybe a later model cab on a year earlier chassis? If the 1967 era was the first of the "Twin I Beam" front ends, just maybe they were using up old stocks??

I think that with the age of these vehicles that it is very difficult to know what is OE unless you know the vehicles complete history. Most of us don't have that info. I believe one of the first steps is to determine that year of the chassis. There should be a VIN stamped into the passenger top frame rail somewhere inside the engine compartment area. As far as a 6 lug, I have never seen one but I am a long way from knowledgeable on those things. Hopefully someone with some real insight can comment.

 

Aussie = all bets are off. I know they were using some locally sourced components then, if not actually manufacturing the whole truck there. It may have been an availability thing. I know in the US Ford ran only five or eight lugs until 97, then an F150 had five, a Super Duty had eight, but the F150 7700 and F250LD had seven. With the last redesign of the F150 for 2004 the five was replaced with a six lug pattern.
What is the size of the bolt pattern on yours?

 

Jared,
Thanks. And just to further cloud the issue, have since learned from another forum that it is quite possible that in reality, the chassis is a 1966 with a later model cab, or at least a later grille, guards and bonnet grafted on! I really only originally bought it for the reconditioned motor and 4 speed tranny, was hoping to salvage the rear Dana diff for a later project.

I will try and get out under it to not only get some axle setting numbers off the rear diff, but may be easier to also remove a wheel, get full and proper measurements of the rim itself. Will post them when I do so.

Cheers, Dave64

 

My 64/72 Ford truck slide does show 6 lug possible for 64/67 F350,7200# and 7400# rear axles. CANADA ONLY. 12" X 2 1/2" brakes. This is only including the U.S and Canada. Ford never gave us info on Aussie vehicles.

 

Got a wheel off yesterday, measurements are as below.

6 studs X 9/16 inch diameter bolt
7 1/4 inch diameter lug pattern
5 11/16 inch centre of rim
Running 15 X 8 aftermarket "Sunraysia" type rims, One inch offset from centre line to the OUTER direction with 31 X10.5 X 15 tyres.

Wonder if they are unique to Ford 62-67?? Vehicle had no spare, only the ones actually on it. Have had a bit of a look to see if anything (Dodge? Inter?) may just fit, but the charts I looked up only go back to the early seventies.

Whilst under the vehicle, tried to clean an axle housing off enough to read the numbers, rusty, covered in crud, but did find one tag on the rear cover of the diff , reads as follows
C7TA-B next line 602890-1 then what is obviously the ratio tag, 4.88

Pretty sure that it is a garden variety Dana 60, but then again, this thing seems to be quite a mixture. As one bloke said, Aussies seemed to be almost a dumping ground for some overseas manufacturers, especially at model changes, like I said earlier, quite possible just using up surplus components.

 

You are missing a digit. Actually it should say:
C7TA-BF....DANA 70..4.88 gears...LOCKING REAR END
OR
C7TA-BR...DANA 70...4.88 GEARS....NON-LOCKING Conventional rear end
Note. With Ford the rear axle and the rear hubs are two different issues. A 8 lug hub would probably fit that rear axle.

 

Just went out to have another look, if any digits or letters missing, never stamped! Tag is complete and readable, as stated in text. NO reference to locker/non locker, NO reference to Dana Model, be it 60 OR 70.
How do you distinguish between the two? My Dana identification diagram shows same rear plate on both, 10 bolt cover.

Bloke on another forum is telling me the serial number on the tag tells you what series, i.e. tag says "602890-1" so HE is saying it is a Dana 60!

As far as fitting other stud patterns, be it either 5 or 8, You not only have to change out the hubs, but rims and the whole shooting match. Then you have to change the front axle to suit the rear, becoming a pain in the butt, then.

Maybe better have a rethink on it all, keep the engine tranny and flog the rest off!

Thanks again for all the valuable info, learning a fair bit about F trucks, especially early girls!

I believe on the axle housing up close to the right lower part of the cover Dana put the series on it.

1967 was the first year that F350's have Twin-I-Beam front suspension with coil springs. 1953/66 F350's have a solid front axle with leaf springs.

1953/66 F350's have 6 lug wheels on a 7.25" bolt circle.

1967/98 F350's have 8 lug wheels on a 6.50" bolt circle. With single rear wheels, these are the same type of wheels as 1953/98 F250, 1969/74 E300 & 1975/2014 E250/350.

Some 1961/62 F350's have a Timken rear axle, while some have a Dana 70.

1963/84 F350's have a Dana 70 rear axle...except for 1979 F350 4WD's that have Dana 60's front and rear.

Rear axle ID tag: Ford # C7TA-B - Dana # 602890-1 = Dana 70 Rear Axle / 4.88-1 / No Limited Slip / 7,400 lbs. Rear Axle Capacity.

Jeff: Text-Section 40.3, Page 4 - Dana (Spicer) Rear Axle ID Chart: C7TA-B (3rd column) & C7TA-BR (4th column) = rear axle parts list #176.

 

Thanks Bill, much appreciated, have copied details
