ok im wanting to put cruise control in my blazer which did not previously come with it. i am being offered the entire setup out of a 78' blazer minus column push button wand. can i take my present wand off and put one with cruise control on ? how much work will this be (wiring) and how much work to put entire system in. also i need to replace my tranny(its a 350) im also being offered one of those, does one have to come out of a 4x4 model, can it come out of a 2 wd, do i have to swap parts ? also i can get my hands on a 700 out of a 87' blazer. will this be a direct swap ? i seen the post about the s10 but this particular 700 could come from another blazer. honestly i have no clue as to the tech side of this stuff so bear with an idiot. any and all info is appreciated ahead of time. thanks. darrenolander galva,il. 1979chevycheyenneblazer 350/350 gettin'down on all fours, 4 a'little x4 play !
