A couple of people in my club are still stressing the 8.75 rears. I offered the older one my Dana 60 that I narrowed with a PowerLock 4.10, 35 splines axles. The rear was narrowed to fit my '87 and the only drawback to the deal is that the bolt pattern is 5 on 5.5" and the brakes are 12" drum. So buy some 16" wheels with the big pattern and run ProStock slicks, no problem. His son turned me down on Facebook saying "...we will never break the 8.75...". The kid has already exploded a 727, but "...he will never break an 8.75...". I used to think I had all the answers, too until I realized I did not even know all the questions

And no, I have no idea what their 60 foots are. I do know they are still running the SBP axles
