What tranny/T-case do you currently have? I'm going to assume a TH350/205. Here is what i can think of that you'll need to deal with. A 700R4 is 1 7/8" longer than a TH350 so this means shorten rear shaft and lengthen front shaft. The output shaft is too long for you to use the 205 and adapter as is so you either need to tear the tranny apart and install the AA shaft or use the spacer (which now makes this set-up about 4" longer than your existing set-up). You'll need to buy a TCC wiring so that the lock up convertor will work correctly. If you keep your original style front driveshaft you should be ok, but if you want to upgrade to a 32 spline output on the front T-case the driveshaft will hit the tranny pan. You need to buy a bracket kit for the TV cable to function correctly (or plan on replacing tranny after tranny). You can swap over from a 700 truck the range indicator on the steering column and adjust it correctly.
