Ok, I just started to work on putting gears on my 8" LS diff, only it is not a "posi" unit it is open. This all started when looking up some info for a buddy's car. Now I have the same problem he has. What types of cars, vans, had an 8" or 9" Trac loc? I will probably be pushing 300 rwhp when I am done with my conversion and with an 8" open rear it is going to suck bad. I priced out a 9" posi rear with 3.55 gears (true bolt in) for $1200 wow. I am sure I can do way better using a salvage yard donor. Does anyone know if the mid to late 70's vans have a 9"? How about posi.
I have seen a few do the 8.8 conversion. I got one for free (well a trade for a C4). Can an 8.8 take a good amount of pounding? D. Hearn talked about one type at over 280#'s and another at #150?#'s. What Mustangs came 94-98 mustangs came with posi rears? I know this is a lot but finding a 8 or 9 Trac Loc from a early mustang, cougar, ?? is nearly impossible now. Can anyone shed some ideas as to where we can look for alternatives on the low $$ side.
