I installed the conversion kit wiper system in my 61 corvette and the wipers work great. What a great improvement over the original wipers. This kit is what GM should have installed to begin with. In any case, the instructions were flawless, and the wiper system installed easily. If you plan on installing a Vintage Air Conditioning system as well, make sure you install the wiper kit first. Customer and technical support was great as well. They helped me get the right wiper switch to fit my application with the AC unit.
