I'm in need of a new wiper switch for my 86 camaro. The current switch is screwy and doesn't work very well. It only has hi and low settings, it does the hi beams and the turn signals, but no delay, and no cruise.

I found a guy selling parts. He has a switch from an 86 but it does have delay. Would these parts be interchangable in mine? He offered to sell me the whole column if that helps at all.

Anyone know if I can change the switches?
