1973 ELDORADO CONVERTIBLE RENOVATION CRUISE CONTROL
 

Need help find parts for the cruise control. In the renovation process, the body shop managed to misplace all the engine parts associated with the Cruise Control. Could any one tell me:

(1) where to find them?
(2) what years (or other models) have equivalent cruise control parts

Also,as a consequence of the missing cruise control, the climate control switchseems to be misbehaving. The mechanic says that that is because the cruise control uses vacuum mechanism which is somehow connected to the A/C vacuum switch.

PLEASE HELP.

Thanks
