Hot Rods Need seals for GM 8.2 drop out rear end 1959 era but cannot figure out what I have.

Refinished the rear end of my Instant T but all the numbers have been previously buffed off. Casting cover on the comes out to December 28 1959. I need bearings and seals but the Chevy ones show 3 inch diameter. I only have 2.750 . All the Chevy ones I see listed are 3 inch . Can anyone tell me what I have and what I need?

 

Didn't the 55/6 housing's use the smaller axle bearing's? 57 and up were bigger.
Don't worry about the date on the Pumpkin, they'll fit anything from 55 to 64.
Try looking for 55/6 axle bearing's.

 

Housing does have a drain plug. Hard to see in the picture

 

Drain plug's can be added easier than swapping housing ends...

 

I took the bearing to a machine shop to remove them and could see no numbers. I should have looked closer before they were destroyed in removal.

 

What axle bearing's did the early Chevy II's use, big or small?

 

On closer look I just have the fill hole. They drain plug appears to added with an Allen screw later.

 

Welp... that's more than I could find on them. LOL!!!

 

Sounds to me like he has a 55 housing that somebody added an Allen head drain plug to, that has a 59 center section?

 

That could be the difference between a dial caliper and a worn out tape measure...

 

On the outside of the hosing is about 2.82 but further in is 2.75". Im not sure where the correct place is to measure. . Thanks for all the replies.

 

Wondered if post #5 in this thread would help you identify the bearings.

I think the 57 has the O rings on the bearing no seal. One year only . Looked on Summet I did see the wheel bearing with one O ring. If I remember 57 has a different axle also. I sold a set a while ago and have the center section in my 59 Corvette. Getting old is not easy.
