rearend identification.

i have been searching the crap out of rear end identification for chevy 10 bolt rear ends and can not find any information on this, here is the issue i got into . i bought a rear end off a guy from a 68 p/u i looked at it and it had trailing arm mounts etc i thought it was odd it was a 10 bolt instead of 12 but whatever it was in a truck and i need to get mine going. got it home and it is measuring 69 inches from wms to wms. it has a 5on5 lug pattern which confuses me. what vehicle had a 69 inch rear end in it and how horrible will this look on a pickup. that is 3 inches wider on each side over the stock rear end.

I looked at that site and it didn't help me. I'm comfuses as to what I should do at this point. toss the rearend in the scrap bin or what. I can't even find anything that uses anything 69 inches. My stupidity for not measuring to begin with I guess.

Re: rearend identification.

what about a Caprice rear axle even into the later generations like the SS[Impala] models did you check those?

Re: rearend identification.

I'm just irritated because I need to get the damn truck done before the new edition to the family is born. I still can not identify this thing. I have only found one set of numbers stamped in it. G57 hmmm... what to do.

Re: rearend identification.

If it is original and came out of one of these trucks... and has 10 bolts holding the cover on... it will be an Eaton or a Dana. Which are completely different animals from a GM 10 bolt.

They were bolted into C20's and C30's... so they will have the correct perches welded to them to fit the 67-72 trucks.

That is what I am taking out of my truck. It was a c20 Dana 8 lug. I shortened the truck and am converting it to 5 lug disc. But apparently In northern California it's impossible to find a trailing arm rearend without spending a fortune. The prices I have found I could build a brand new rearend from scratch lol
