what does this entail to remove cruise control from a donor vehicle and install it again in a vehicle previously without it. is this practical and would it be better to purchase an after market kit. im really looking for original, working equipment. anyone with comments/advice or a system to sell please let me know or help. all is appreciated. thanks ahead of time and happy new year ! darrenolander galva,il. 1979chevycheyenneblazer 350/350 gettin'down on all fours, 4 a'little x4 play !
