I have a typical SPOA and will soon do a RUF....I was told that I need a 1" spacer for the rear drive shaft, assuming bc of a spoa , and (2) 3/4" spacers for the front drive shaft for the RUF...
I don't have a spacer on the rear drive shaft and it seems to be OK?....
So I guess my dumb sounding question is how do you know when you need a drive shaft spacer? I'm assuming it's not ad simple as " you'll know" because I don't have one now and was told (by a popular vendor) that I should have a 1" rear spacer for my spoa...
