I've searched here for a few days now and know the answer is here somewhere but have not really nailed down ALL of my options on a rear end swap. It sounds like the 2nd Gen is the best option, but what are my other options if I can't find a 2nd Gen? It would be great to find a Posi with the optimum gears, but not a necessity, just looking for something other than 2nd Gen that can be slightly modified to fit my 68. Nova maybe? Anything BOP?
I would change the gears and insert a Posi unit, but rust has got the best of mine.
