87 half ton is essentially the same although batteries are side terminal. One work of advice, if you do it that way, ise an aftermarket stud in the RH battery, high current draw on the factory dual wire terminal wil melt the battry, plus it's hard to avoid stripping. I put in an after market stud with nut that the cables attach to. Next time I'm using the military busbar on the firewall....
