12 Bolt Rear End ID?
I bought a rear end online. It was supposed to be a 70 Chevy 2wd 6 lug measuring 62". I am putting it under my 1950 Chevy Truck.
The rear end arrived today measuring 64". I called the company and they don't even know what they sent me. Here are the numbers... GM 52 NF3896838 TDE 11 05 W Can someone help me ID this thing? I have read that Chevy changed rear end widths 1/2 way in '70. There is a wide and narrow. |

Re: 12 Bolt Rear End ID?
Dunno what the GM 52 means. I bought a rearend a couple months ago with the ID of GM 51 NF3896838. It is a 3.89 gear ratio with a posi. Best thing to do is pop the rear cover.

TDE code is a 3.07:1 ratio for 1970 if it hasn't been changed.
