My jeep is a CJ-3A 1950. I estimated the built date around late August 1950.
Serial # is 56908





Hope this help

Mine is set back about 1/2" like you show in the top photo. Hard to see for the rust/paint so I outlined in red.

Thanks for the replies guys!!!

JBCarney I have one question. Does your long rib end flush with the front edge (bottom photo) or is it set back by about 1/2" (top photo)?

Serial number 451-GB1-29540. Wheel housing ribs same as first picture. One long, one short.

Okay, I'm going to try this again, maybe I can get it correct this time  :-[

Looks like the length of the long wheelhouse rib changed between 451-GB1 152xx and 451-GB1 24316. That narrows it down to the early 1951 model year.

Anyone else out there with an early 1951 CJ-3A to help with this survey?

Thanks,

The long rib on 451-GB1 24316 is a 1/2" back from the edge. Looks like the change was between 24316 and 52xxx. Anyone else have a 1951 CJ-3A to help document this change point?

Edit, Looks like I got that second serial number wrong. 1955CJ-5 can you verify your serial number for me?

Thanks

My '51, #152XX has the long rib that goes all the way to the edge...short rib appears the same but there is a hard top and I can't get a ruler under it....

The two long ones on my 49 go all the way to the edge. They don't stop just short.

Here is the drivers wheelhouse on a 1950 tub. The long rib is flush with the front. Unfortunately I do not know the serial number for this tub.

F Bill

My 51 3A Ser # 451 GBI 27079 (for those that can tell when it was made)  Has the same ribs on the wheel housings ending about 1/2 inch from the end.  The ribs are also like in your picture in that the edges are steeper on the side to the outside of the body and more gradual to the inside. The floor looks to be same hight ribs as the wheel housings ( smidge over 1/4 inch) but the sides of the ribs are the same.

Hope that helps.

Thanks Ryan. It looks like your 3A has the later rib that ends about 1/2" from the front.

This is my 1951 3A and from what I can tell the serial number dates it to around May of '51. The body work done as part of the overhaul affected the ribs (long story) so I would not trust measurements now. Here's the best pic I can find of the area in question prior to it being introduced to a maniac with a cutting torch.
