A buddy of mine gave a 10-bolt Nova rear to me for a swap-in for the original one in my 46-chevy 1/2-ton. Is this the easiest swap...with intentions of a very cheap and simple update in rear gears/suspension? Another friend has a 43 that he mentioned a 55-57 chevy car rear fit perfectly like it was meant for it and works fine for him. My plan is to just go with discs conversion up front with stock spindles. Keeping the inline-6 and 3spd, possibly early 5spd if I can find a good one. Trying to stick with the K.I.S.S. method. Any suggestions or experiences would be greatful.
