what a bunch of babies....geez.
back to the sprag; my understanding is;
1. add a bolt in to prevent the oem from spinning in the case,or damaged case from one already spun
2.buy a "good" bolt-in if hi hp levels,[added rollers] more $$$$
3.the cheap four bolts are avalible,for home do it your selfers 80.00\
and they have ferrels to kinda take up the hole to bolt slop
4.good ones have shoulder type and added number of rollers [c-6 unit]
have CRT do the trans.. ...mike
