You'll have to make the output shaft on the 700R4 look like a TH350 27 spline. Then you'll need the tcase, shifter, TH350 to NP205 adaptor, coupler sleeve, and driveshafts. The crossmember should work. Usually the best way to do it is to get the whole tcase assembley and driveshafts from the same donor vehicle. Your 700 will have to be disassembled to change the output shaft. In the kit you get a spacer and studs also.
