Lengths of Rear Radius Rods?

I'm trying to put together a table for the various rear radius rod lengths, part numbers 4750. I believe the '41s are the same length as the 1942, 1946-1948s, but have a different rear casting.

Pictures would help too.

Thanks,
Glenn

1932: bolted to the bottom of the axle tubes
1933-1934: same as 1932, but slightly different construction
1935-1936: bolted to the bottom of the axle tube with the addition of the rear spring hanger being cast into the bones (very popular for hot rods)
1937-1940: bolted to the ends of the axle housings, but went nearly all the way to the end of the torque tube (need to be shortened for AV8's, etc.)
1941, 1942, 1946-1948: bolted to the ends of the axle housings, but only went half-way up the torque tube.

32:
33-34:
35-36: 62 1/2" front mounting hole to center of axle
37-40:
41, 42, 46-48: 44-1/2”-3/4" front mounting hole to forward rear mount hole.

Bump for Glen. I have all that stuff, but my recent move has my life in limbo. Parts are in sealed crates all over the yard so I can make a shop out of a pole barn. God knows which crate to look in. Hadn't moved for 48 years, and it now shows I'm not very good at it.

Someone must have some rods around to fill out your chart. Thank you for your effort.
 
There are 2 different styles of rear radius rods for 1932. Both styles bolt to the bottom of the axle housings. The early style (B)have a bend at the connection to match up to the mount on the axle housing. The late (18) style are straight and the mount is angled on the axle housing.
 
Yes, attached are a couple of pics of the early style. I can't locate the late, straight end type, 32 to34s.

I believe I may have some of the later 32 - 34 ones - will check tomorrow and supply dimensions if I have them. There are very few actual late 32 rear ends that I've seen - especially true if you want to find an original late 32 torque tube and driveshaft.

I was lucky enough to find one for my 32 Cab - as I didn't want to run the early rear if I had a choice. The early rear is much weaker as compared to the later one.
