i know true trac makes one for your 7,5 inch rear end....
as for ratios v6 5 speed 2wd (5 lugs) came with 3.15 and the lager 8.4 rear end.
i have the trd lsd in my 6 lug 8.4 housing. clutch type though no like the gear driven trutrac.
if u can find a taco at a junk yard with a tach and it is a 2.4/2.7 (4 cyc) it will be plug and play.
