[DeTomaso] The Clutch in 5533

[Asa Jay Laughton]

I've received several emails as of this morning, mostly privately, that 
reflect the same or similar advice as Forest.  I'll be looking for a 
shop here in Spokane that can service clutch parts, not just sell me new 
stuff.

Thank you to everyone who provided insight.... including you Paul.  :)

If so I would take the pressure plate to them and have them reface the pressure ring and rebuild the assembly. If it is the original pressure plate it should have a steel ring as opposed to cast iron and would be better rebuilt than a cast new one.
