<VV> Re: re;clutch problem

[Bill Meglen]

Tom,

Received a replyto my post  from O. B. Stewart quoted below leading me 
to believe the "ball stud" is my problem.  Would welcome measurements 
of early (flat) pre (1964) ball studs vs. "late" ' 64 recessed flyweel, 
comparative lengths so I will know how to shim my 1963 ball stud to 
match the recessed (late) flywheel.  If there is a differenced in "ball 
stud" physical configuration I will need to acquire one. I understand 
they are only available used.

Thanks for the offer to measure your inventory of "difs"

Really appreciate your very responsive commnts to my post.
