Tom's Differentials sells a carrier cap kit for about $70, it upgrades the driver side cap, and comes with 1/2" cap screws for the driver side, 7/16" upgrade cap screws for the passenger side.

On a side note, when the new housings were introduced, Tom refused to sell them because in his opinion, the cases were not within usable tolerances for his standards. That was the last word I had from him on the subject 3-4 years ago.

I have 2700+ passes on my old A-Body 12-bolt with the Tom's cap kit, no troubles, and have a car out there that is 3200# + driver running 8.60's with the old M/W cap kit, he kills a Pro gear about every 300+ passes, but no housing troubles.
