MattKab,
if you have a single sided IRS tranny...keep it. It is supposed to be the best IRS case. It has extra ribs there and should be stronger. When I was planning my tranny I was told to find such a case by Bruce Tweddle who knows trannies pretty well and he is the one that sells the ZFs to everyone I know in the US/Canada. The only better option for a case would be the Autocraft case.
Another week point with all trannies is the R&P. I believe that you can only get an aftermarket 4.125 new somewhere. All the others are used and you have to find a good one.
