I have what is supposed to be a 55 Chevy BelAir rear, it has 3725899 cast into the third member, also what appears to be F202. Any info regarding the rear and any info on parts and suppiers for this unit is greatly appreciated. There does NOT appear to be any drain plug. Thanks very much, trying to keep the ol' iron alive, bulldog.

howdy there,



F202 decodes to June 20, 1952 or 1962, etc

got a pic of diff housing ?

it could be an old chevy eaton variant such as in the '72 and older gm trucks etc, i really dont know what was used under the 50s cars, as i am really a 63-up GM truck nut mostly and i know all about the rears used under those haha., watever it is im sure its the same axle as under the 57 4 door 210 we have sitting out back because it is stock original untouched, unlike our 57 bel air gasser conversion that has a ford 9" axle welded under it.

try www.randysringandpinion.com for parts they are good for older axle parts i am pretty sure.

I will check out those links, very familiar with Randy's ring and pinion, good place for the old iron rear end parts, sure hope its not a 52, I mean thats even older than me, just ask my 39 year old wife!! Any help in determining if its 52 or a 62 would be greatly appreciated by any one out there. Will try an get a pic up of the diff., still working on getting pics up of the old hemi before I tear into it, thanks again for the help, very much appreciate it!!

3725899 was the old drop-out-type rear Chevy used from '55-'64.
