why should cars be so lucky ...... haven't ran across any car 12 bolts must be why they are so hard to find.....1981 ok.wonder what year was the last for cars????

Trucks didn't really need that much strength in the pinion area as they were low powered. Chevelle's with 396 and 454 backed by 4speed it would be warranted. Last year for a 12bolt in a Car would be 1973. 12bolts for cars are priced like gold. Moser is making them again though.

If you really want some strength for that much power and use slicks, you need an aftermarket setup. I don't think a stock 12bolt will hold up to that kind of abuse for long.

How about a 9" housing with Stranges' 12bolt drop in. Lighter, less hp loss, no c-clips
