GM rearend identification

Hi,It's been a while!I'm trying to ID the rearend in my car.I was told it was a late 60's chevelle.(It's been narrowed,and I think the axle codes are gone).There are no nuts on the rear of the housing and the only number is on the differential.The number is 3790614.Any ideas on what it is?Got on a site(chevelles.com)but got no info.I'm hopping brake parts are available.Thanks

Hi. I cannot help as far as the actual ID of that rearend other than to say if it has no bolts on the back such as a 10 or 12 bolt might have then perhaps it is an older style Chevy such as a 64 Impala or BelAir.
Is it possible you are running a Ford 9"?
Anyway the big thing is that I am sure what ever that rearend turns out to be you will find the brake parts you need.
There is a Baker Supply in Victoria I believe. If so they will be able to help you if you go there at a time when they are not too busy. Take your shoes etc to them for a comparison. Once you find the ones that match they can tell you what those parts fit.
A box of donuts might be enough to get them to do a bit of searching for you. Good Luck!

I'm thinking it's a Ford 9 as well, only because I've never heard of anyone shortening an Impala/Belair rearend. Do you know if the axels are chevy or ford bolt pattern (but that still may not tell you since they could be custom too). Take some pics and post em on the thread. Some of the back and then the case/pumpkin.

does the 3rd member come out of the front????? if so its either an early GM, a ford 8 or 9 inch rearend. If you have to use a wrench on one of the bottom bolts to get it out, it means its a ford 9inch. and like tubbed said a pic is worth a 1000 words...joe

I have one on my 58 Vette.

I have the same serial number on my 58 Vette rear axle. I know it's not a corvette axle and I'm wondering what it is?

If anyone knows for sure let me know.

I would like to replace it with a 58 vette rear axle.
