I have recently bought a 90 trooper 2.8L and have had the computer rebuilt but I have found out that both the proms in the computer are toast. Easy enough to fix if I can find the parts. Unfortunately I can not find any. I am curious if anyone knows if the proms from a Chevy S10 with the 2.8L would work. The whole drivetrain is GM so I can't see any reason for it not to but I don't want to spend the money if someone else knows that it won't work. Thanks for your help.
