So this has been covered before, but everyone has different theories about this.
I am about to convert my r32 gtst from a rb20 and box to an rb25 and box and have been told I need to mod the tailshaft to fit. I want to keep the cost down, so im looking at doing this the cheapest way possible. Im not going to be running crazy power, so I just want to modify the stock tailshaft to fit instead of going custom. Now I dont want to know your theory on it, just want to know what worked for you. I know I need a new yolk to fit the box, but do i need to shorten the shaft as well? If so, how much? Because the car is my daily, i cant have it off the road for any longer than a weekend, so i cant put motor and box in then measure it. I need to have it done and all ready to drop in.
Thanks in advance.
