[DeTomaso] Weirdness with my Cleveland ...

[Garth Rodericks]

What about replacing the roll pin with a carbide drill bit shaft/shank? Wouldn't that work and be a more permanent fix?  
 
Someone on the PI board reported that his roll pins would not hold (even double pinned) so he went to a 3/16" hardened bolt and locking nut (never a problem again).
 
So, would it work to just press-fit a hardend drill shank?
