@dunfire Patrick, none of those numbers appear in the Identification number section of my 1949 Master Parts Catalog. I can check a newer list for you in a while. As for the possibility of 1947 rear axle (wheel to wheel) fitting under an AD pickup truck, I can tell you that the track width is different and the spring mount spacing is different. This info is relevant to a 1951 1/2 ton pickup and I am assuming it would hold true for the 1954 also.

I once mixed parts and installed a 1954 Power Glide gear set in a 1951 pickup. I plugged the 3.55 torque tube into a 1948 housing and had to relocate the mounts on the housing.

Attached is a screen shot of a page from the 1947 passenger car vehicle information kit on gmheritage.com. It shows EA1206 is a passenger car 4:11 rear end built December 6th.  I checked a few other years and found rear ends for 1941 start with “A” but can’t make sense of the other letter and numbers provided.  Hope it helps a bit.  Mike

Thanks guys

@35mike Mike, would you mind if I gave this guy your number to call you?  He called me last night and I am unable to ascertain what exactly to tell him to mitigate his issue.  Also, one of our members has a 1937 Chevrolet 1/2 ton and needs 6 hubcap clips for two wheels, do you have any with rivets and how much would you like to get for them?  

Thanks,

@dunfire Patrick, I would be glad to talk to him. There is a common perception that all hubcap clips are alike. The Master Parts Catalog shows a clip (spring, in the catalog) that fits 1937/1938 passenger and 1/2 ton plus some 3/4 and Ton trucks through 1942. Jim Carter sells clips that are close enough to work, but are not exactly as original. He sells them as a "one size fits all" item. I needed some for my own use so I harvested them from some junk wheels. I used rivets that are made to attach sections to the sickle bar on a hay mowing machine. I have plenty of rivets and I would be glad to send a handful to him. The wheels for 1937/38 passenger and 1/2 ton are unique. The centers have 8 "spokes" where they meet the rim, instead of the usual 4 that is the common arrangement.

Have him call any time.

I have spare 1937-38 Chevy car wheels.  Are they the same ones used on Chevy 1/2 ton pickup trucks?

Most trucks I have seen have different wheels than the ones used on cars.  Were there optional wheels for trucks?

@headlighter Tom, All 1937 and 1938 cars and 1/2 ton trucks used the same wheel, which was the 8 spoke design.

In 1937, Chevy introduced their 3/4 and 1 ton models. These trucks used the same 6 Bolt pattern as the 1/2 ton and passenger cars. The 3/4 ton trucks were fitted with 15" artillery wheels. The 1 ton trucks had 14" rear brakes so they needed a 17 wheel to clear the drums. This wheel has 8 "spokes" but is a 2 piece design with a retaining ring.

I believe the 3/4 and 1 ton models continued to use these respective wheels for all of the prewar years. The 15" and 17" wheels used the Passenger size hubcap.

Thanks for clarifying.
