Ive done 3 of them & a freind has done 2 & we didn't use a spacer. If you modify the trans. acording to the tech tips It works fine. The main thing is to grind the splines on the input shaft so the disc will slide back about 1/2 in. If you have a good pilot bushing in the crank you will support the shaft as well as with a spacer.
The only advantage of the spacer is you could change trans. without going through the modifications, but you still would have to drill out the mounting holes.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
