m-21 to tko 600

whats the difference in front bearing retainers,length and od.

Why? Do you think they would interchange? I have a TKO one somewhere, swapped it out for a HTB

i have all new hyd. clutch w/ram release and broke the muncie. I was told crb would not work,so I am trying to figure why,length ,throw etc. will work so I can only think od. of retainer is different
