Like said before, if the car never hooks you'll likely never break the 8.75. If it hooks at all, it won't last long. Your power w/ a manual trans WILL kill an 8.75...not if, but when.

I have a Moser 60 in my cuda that I bought in either 2003 or 2004. No complaints, but if I had to do it over again, I'd get a Strange S60. The only reason is the Strange unit has side adjusters for setting the backlash which is much easier to work with.

I have 2 road runners that I used truck Dana 60 rears and cut them down to fit. Work great and a lot cheaper if you don't mind the extra work.
