I actually was under my 66 tonight fitting the 8.8 up under there. I bought the summit racing spring perches and they're horrible...they're split where they bent them over. I'm gonna return them....I'm gonna get the afco units.
as for the ds...I haven't gotten that far, but research tells me the 8.8 is perhaps .75-1" longer so I'm going to use my old c4 driveshaft. I already shortened it 3/4 of an inch for the t5 conversion, and there is plenty of yoke to slide up still....the only thing that will need to be changed is the end at the rear...for that I've got an old fox driveshaft with the proper flange to bolt to the 8.8...I'll just need a conversion u joint that mates the fox pinion ds flange to the old style 66 driveshaft. I don't have the part # yet, but they're fairly easy to find from what I've read. I've also heard that you can buy a conversion pinion flange for the 8.8 to convert the 8.8 to the old style u joints with the horse shoe style clamps, but that's not the route I'm going to go.
