Ok so here is the deal I want to get an aftermarket steering wheel and tach but I need to know what I need to get them to work. (on a 66 Riv)
From what i've been told, the tach gets wired into the distributor. Steering wheel should be an easy bolt on, possibly might have to drill a few holes. I'm not certain as to where the tach wires go in the distrib. but i'm sure someone else around here does
As to your question, you probably wont need anything else besides what is with the aftermaket parts. They usually include all the parts (and instructions, but who needs instructions eh? :Brow: )
