I'm planning to build a TH350 (probably a TH350C) for my 69 C10 and installing a Gear Vendors OD. I currently have a greasy 700R4 from an 88 G-van sitting in the shed, *supposedly* a good used unit. Would it be worth tearing into it to steal any upgrade parts to put in my TH350? I've heard about using a center support from a 700r4 in a TH350 for the wider sprag clutch, are there any other parts worth swapping or would I be better of just selling it as a whole unit and buying new upgrade parts? The truck is a mostly stock 350 and I'm going for just a rock solid daily driver trans, maybe occasional towing and a yearly burnout.
