I have read that the BOP 8.2 is very durable and can stand up to an "enhanced" 400. It has beefy axles that bolt in, therefore no "C" clips. Plus it has stonger U-joint straps. It's better than a chevy 8.2, but not as strong as the 8.5 10 bolt.

thanks for the link firebird red. After looking at the link, I'm not so sure the Auburn Posi will work with a 2.78. 2.93 must really be the cutoff, like steve G was saying.

thanks trauschu, I'll try to find out if it will fit my TH350, and how much shipping is.

I could always have my driveshaft lengthened, replace the u-joint, and balance it for about 200 bucks, maybe less.
