i got a dodge nv4500 and want to switch it over to chevy nv4500 the only difference is the shafts in spline and length. what i want to know is since its just the shafts i have to switch. could this be done by a novice mechanic or is it a bit to involved for me to tackle myself and should i just take it to a trans shop for the switch i already located where to pick up shafts at
