Welcome to the Forum

GM used a couple different configuations in '84..a repair manual (Haynes,Chiltons or All Data) may be of some help..It may be a longshot but if you can find the RPO code sticker you might be able to match it against 1 of theseRPO CODES

Or maybe someone else in this forum may have the same year truck and can help you out better than I can...........my memory isnt what it used to b
