Only info I could find is from an old (late 60's) Republic Gear Co catalog for replacement axle shafts. Their applications list two rear diffs, both Clarks, but there could have been other suppliers.

The first, 1951-53 Diamond T 322, is a Clark model# R755, Republic axle shaft #S1650F, Clark shaft #36863H, Spline count: 16, Spline dia. 1.625", length 35".

The second, 1951-55 Diamond T 322, 404SC, 420, 509SC, is a Clark model # R1000, Republic shaft # S1502F, Clark shaft #116863R, Spline count: 16, Spline dia. 1.750", length 36.5".

I have been unable to find any pics or other info on these these Clark axles. Not even sure if that is what you have, but you could pull an axle & might point you in a direction.

Not sure but I think this is the same Clark that makes the planetary axles.

Cutting any original metal is what I'm trying to avoid. With these things being relatively hard to find parts for it definitely something I want to avoid. That being said couldn't I just get lift springs made or body lift or both to avoid tire-fender contact. Just my personal taste but I really dig the whole front tires sticking past the fender look on the front. So long as it's not extreme. It gives it a military truck kinda look IMO. Not to mention that kinda a rat rod look. I got a long build ahead of me and lots of time to change my mind for sure. I'm sure in the end I'll end up seeing it your way.

It's my personal opinion that 24.5s are going to look stupidly large and going to force you to cut up the front fenders. I'd find me a Ford F450/550/650 or something similar and set that DT cab and sheetmetal on it. Instant rod with modern dependability and modern road speed capable. Been there, doing that!

If you do go the modern route, save the old stuff for someone that is doing a restoration.

A whole frame swab was a idea I have tossed around. It might be more cost effective as well. A little while back welderup in Las Vegas built a diamond t. Essentially creating what was in my head. The only diffrence is mine is a 50 t 322 while thiers was a 47 509.

Be aware that most 10 lug axles are going to too wide for the frame and in the front for the wheel openings. I seen a few try it and it looks off. Not to mention you'll need to move spring perches.
The frames on these old trucks are narrower than on modern medium and heavy trucks, which are all close to 34".
Not sure how 24.5 tires are going to fit the fender either.
Hard to guess to the real maker of the axles, My K-7's have an IHC number but not sure if IHC made them or not. Diamond T shared some stuff with IHC as they were both Chicago based companies.
You might be better off swapping the body onto another frame if you are not restoring.

That's very sad to hear. These trucks are one of the most beautiful trucks of that time period. Yes the dashes are gorgeous I plan to restore mine. The truck has a Hercules i6 in it. But unfortunately it is seized good. From what I can tell looks like the radiator blew and someone drove it till it locked up. The truck was on a farm in Montana all its life 1 owner. Until I found it online and brought it over to Washington.
