alright guys, i just came back from the junkyard and they will sell me a unit for 25bux. there are a couple of cars there, first is a lt1fleetwood with drum brakes if i remember right. there is also a tbi fleetwood and a couple of caprices. how can i tell if they have g80's? i looked in the glovebox like in my truck and the RPO codes arnt there. so if i find one with disk brakes will it automatically have a posi or what do i have to look for?
