I machined a 3/8ths spacer because I had a twofold problem. Not only was the shaft to long but the splines wouldn't accommodate my 11" dual friction clutch. The first clutch would bottom out on the splines (input shaft) before the tko 600 would mate up to the Quicktime bell housing. Even though I have a 557 cu in 385 series. I have a Ram FE aluminum fly wheel and an 11 in. dual friction clutch.
If you go to the 429/460 form I have some pictures.
