[V8] Dizzy Help

[Stafford, Kenneth A.]

 In addressing my oil leaks I discovered that the driver's side dizzy was
leaking around the shaft seal.  No problem...just knock out the pin holding
the drive adaptor onto the shaft, remove the adaptor, pull out the shaft and
replace the internal seal...  Turns out that pin is TIGHT into the shaft and
in extracting it, I destroyed the bonded plastic (anti-rattle?) outside of
the drive adaptor!  So...does anyone have an idea of where I can obtain a
replacement drive adaptor (or complete left dizzy assembly)?  I shudder to
think about what it would cost to replace through the dealer!
