LMC does sell the ones your looking for but like you said they dont list what lamp is being used.
Call them and ask
I just bought the complete set form them for my '87 and they use a 9006 lamp but thats a dual headlight system.
BTW the units LMC sells are of a high quality and fit really well
I had a set in a S10 like the one in the pic above and they were some elcheapo brand and they didnt fit the light bucket real well and the trim ring that holds them in was loose so i had to wrap the light assy. with some tape to compensate for that.
