I bought an open 1.8 diff for my car from Planet Miata, but now I need to make my last payment for school. It's in good working order from what I can tell, but it's just the guts in the front half of the housing. It doesn't have the carrier to bolt it to the car. The gear ratio is 3.9:1.
$400 shipped, obo.

late 70s or early 80s truck... and while the r/p would swap, the actual diff assembly wouldn't.
since it came from PM, either
(1) they pulled the torsen from a 6-spd rear OR
(2) it ain't a 3.90 <--most likely

here's a question i SHOULD know the answer to... while i prefer to have a limited slip rear, my main concern right now is that when i get the new injectors in and start running more power, i'm going to make short work of my 1.6 rear.
the open rear should stand up to the power the same as a limited slip unit, correct, as the 6" vs. 7" ring is the factor at hand? this of course assumes i'm not rockin peg leg burnouts and drifting like it's going outta style. right?
