I would like to add cruise control to my car, using factory parts if possible.

Is there anyplace I can buy factory cruise components from for a 1972 Cutlass?

 

YES..........................................Check flea markets, e-bay and other forums such as this one...there are lots out there looking for a new home...

 

Parts are out there - just hidden. It may take time to piece a system together - you will prolly not find a complete kit of all good components...

It took me a year to find all my parts and restore them.
