Okay, so I've discovered the hood interference problem with the windshield wipers on my '96, and I want to know if anyone has used RockAuto for ACDelco replacements. There are multiple choices and I can't decipher which is the OEM spec. If anyone has the actual GM part number that would be great. They list the following at RockAuto:

89001048 (std)
89001011 (perf)
89000978 (all-season plus)
19114809 (beam)
19162953 (beam w/spoiler)
 
I've never found a non-GM wiper blade that cleared the C4 hood. I don't know if GM even sells then now. Good luck with your search.
 
Isn't AC Delco GM?
 
If anyone has an original and can take a picture and post it here that would be helpful. Better would be a caliper measurement from the top of the attachment hole to the top of the arm. Best would be the correct GM part number. I got a pair of 89001011's and they don't look much shorter than the Michelin's that started this whole mess...
 
I bought new ones from my local Chevrolet dealer about 3 months ago. They had to order them and they gave me a great price.

I had the same problem during a rain drive and stopped at an Advance Auto Parts store. I lucked out because the clerk also was a C4 owner and knew exactly what the problem was. He put there teflon wiper blades on and the problem was gone.

I could not find any name on this but perhaps this picture will identify the blade at Advance Auto

Good Luck
