    OK, I'm about to purchase a TH400 w/ NP205 adapter from a member here. I need to know what mods I will have to do to get this beast of a combo to work in my 84 K5(350/700/208 10 bolts). What kind of driveshafts mods are nesscessary, shortening, lengthing? Do I have to get a new crossmember or will the stock one for the 208 work? Will the stock 700 shift linkage work with the 400? I belive that the cooler lines are the same. I plan on getting the kickdown switch that mounts on the gas pedal, and I know I have to run a Vaccum line somewhere. I'm guessing I need to get the shifter for the NP205, but will it fit in the existing hole?? That's all I can think of now....any other tips & tricks would be great. TIA
