"F" distributor

[Neal Thomas <mr300f@xxxx>]

About a month ago my distributor began making odd noises which I could 
hear with engine idling. The engine ran okay but the tachometer began 
bouncing. After a short period it stopped working, so now I'm guessing 
that the mechanical drive portion of the dist needs to be rebuilt, if 
that's possible. If it is, does anyone have suggestions as to who might 
do this type of repairs?
Thanks
