  1. I am having a ridiculously hard time finding a gm 8.5 at the local junkyards where I'm from. I've checked other cities nearby and nothing. I need a 1968-1972 10 bolt 8.5 for my 70 skylark and the best I could find was an 8.5 out of a 77 cutlass, which I am now aware will not fit. I've been scouring the internet for the past few days trying to find a housing (I don't need the gears or anything like that) and I cant find anything in my price range (roughly 200 dollars, give or take a hundred bucks). Do you guys have any ideas? I'm getting kinda desperate. If I go down the route of making the 77
  2. Is there any way to fabricate it to make it fit? roughly how much would that cost?
  3. I just got a bunch of dudes getting ticked off that I wasn't a purist
  4. I made two posts, one about the transmission and the other one about the differential. however, my computer is pretty old and tends to freeze so it may have posted the same question multiple times
  5. I have a 1970 buick skylark with a chevy 350 (yes I know, Im not a purist) with a th350. I'm on a bit of a budget and I wanted to find either a 2004r or a 700r4 from a junkyard to put in. It is a semi daily driver/strip burner with a gm 8.5 posi with 4.11 gears in the back (yes I know its a lot of gear, which is why I want overdrive). I can do all the work on my own if it bolts right in, but I was wondering how much fabrication would either one need? which one is better on gas or drag racing? Most importantly, which cars would be good donor cars with this kind of thing?
  6. hard to find a 12 bolt around here and a lot of people online are charging and arm and a leg for their shoddy pre owned ones. I am planning to swap the engine in a few years to a 454 (I have a chevy 350 in it currently) and many people have told me that the 8.2 probably won't hold for long with any higher horsepower applications. learned that an 8.5 with a posi would be a good way to go, as it can handle higher horsepower and there is a lot of aftermarket support for it.
  7. I own a 1970 skylark with gm 8.2. I am currently looking to swap to a gm 8.5. A friend told me that a good swap would be to take a differential from a 77 cutlass. Question 1: Will this be a direct bolt in? If not, how much would it cost to adapt it to fit? Is this worth the effort or should I look for a different one? question 2: Are any parts interchangeable between the two? I remember reading that the axles and shoe brakes are interchangeable, as they are both bolt in axles, but this sounded like fishy information. Question 3: If this differential will no
