Fan question

Going fron /6 in my 72 scamp to a 5.9 magnum with v belt set up. Needing a fan. What fan will work for this set up. Its just a stock 5.9 nothing special. Will the slant 6 fan work? Or What JY fans should i look for. I still have thr fan for the 5.9 would that work? Also will a factory a body shroud work?
