BIG project drive train

[spencer_41188]

i got me a 87 r30 and i wana make it 4 wheel drive and i got a 1980 k35 for a parts truck. the 87 has a 383 stroker, 4speed and will soon be a nv4500 i got the adapters from aa so the np205 will bolt right up. the 80 has a 454, 400, np205, and a dana 60 and all the other small parts i need

my question is will the spring hangers from the 80 fit on the 87. and the rear shackle is there a hole for it in the 2wd frame, should i cut one out, of fab up a bracket that bolts or weld to the bodom of the frame, i dont wont a lift but level i can live with. i know i got to tear it down to just frame hornes and a crossmember im keeping my sterring box on for crossover steering, i got a **** ton of body parts im swoping over so i might as well pop the cab and paint the frame spray bedliner on the underbody all in all its a big project and i havent found a forum for the 2wd to 4x4 convertion but i have seen one for the nv4500 swop but yea lots of pics coming when i get home and start on this
