Does anyone know the parts and part numbers to swap these parts on a 1986 coupe? I've searched the forums and found some part numbers, but most of them are no longer valid.
I know I will need the L and Rarm assemblies and the L and Rblades, but do I need to replace anything else (like the wiper transmission(?))? Also, what are the recommended lengths of the GM wiper blades to be used?
I've checked with my local Chevrolet parts guy, Chris May at Superior Chevrolet, and with GMPartsDirect.com and this is what I found:
1996 LH Wiper Arm - 10288071 - There are like two left in the USA
1996 RH Wiper Arm - 10288072 - Does not exist. Period. Anywhere. Even Vintage Parts Inc can’t get it.
You can still get the 84-94 wiper arms through GM (LH - 22144265 and RH - 22144264). I paid $75 each for mine.
To prevent any wiper collisions; I am going to install Trico Exact Fit 20-2 on the passenger-side and 19-2 on the driver-side. These are low enough to clear the hood when at rest. These wiper blades can be found at any Advance Auto Parts stores.
I hope this helps anyone out there who is looking for information on this conversion.
