Just got my new 383 HSR built and putting out 492hp. Built the 700R4 up pretty solid and now I am moving on to the rear! I have looked in past threads and could not find what all has to be done for the conversion. For sure the diff and batwing and the driveshaft and ladderbar? Not sure what all i need to aquire to make the swap happen. Also what years of the batwing diff and ladderbar will mount my 700r4 and bolt up to suspension? Thanks for the help!
