Sorry to say guys but Dana DID
make rear end's for GM!
In my garage, I still have the Dana 10 bolt posi that came out of my '67 Elcamino.
Sure it's only a 10 bolt, none the less it's a Dana. By all apperances
it looks like a regular 10 bolt, but on the inside it weird. No other 10 bolt carrier, 8.5 or 8.25 will fit in the housing.
When I went to rebuild it over ten years ago the dealer told me they discontinued selling parts for that type of 10 bolt. I called the GM customer relations office as suggested by Harrington Chevrolet in Everett. They told me that GM was lured by the Dana Corp. to build their limited slip differentials. Unfortunatly the 10 bolt contract lasted for about one year untill GM dropped them due to poor performance. Subsequently they renewed their contract with Eaton.
Nobody and I mean nobody
makes a rebuild kit or carrier for it, period end of story.
Now you can call me a lier or tell me I'm full of B.S. But if you want to buy a plane ticket to Seattle, I'll drag out the 10 bolt rear end out of the garage. BUT,
you'll have to buy all the beer me & my friends can drink.
