Swap cruise control from 86 GMC C3500 to 77 Chevt K20?
I'm sure I'd need to swap the carbs, but could it be done?

Are they two different systems?
Are any components common to the two?

you can use the 86 setup in the 77. The harness is altgether different however as are the transducers. There are also circuit for dis-engaging the lockup converter-are you using an OD transmission?

The 86 uses a THM 400 I think and the 77 came with a THM 400 originally but now has a THM 350.
