Default weatherstrip

I ordered and installed the front windshield A pillar and rear halo B pillar roof seals. I ordered the cheap seals from corvette mods and they fit perfectly after properly removing all the old weatherstrip. Just wanted to let people know not to be afraid of the "cheap seals". My car only sees maybe 3-5k a year and not much bad weather so I guess I'll keep you posted on how they last but as far as installation they fit perfectly. They came in a box with corvette America stamped on it. Just an fyi thing cause the seals I bought were half the cost than from wilcox. So if your like me and wanna cheaply fix your c4s weatherstrip I'd recommend them.

Did you do water test?

Start off with water hose to check for leaks. Adjust if so. Or if good, then leave it out in some rain storms.

One problem I've heard some is the B pillar not sealing well to the glass. There is some adjustment there, but not much. Plus that adjustment screws with the A pillar side adjustment.

Also what did you use for the top corners on the A pillar? Looks like to me that's a good place water can get in at. I don't like gluing stuff in. But when I had to lift up and then put the OEM A Pillar back down. I used bedding and glazing compound under the corners there, then ran a small bead of RTV along the top at the corner from top retainer to side retainer. Then pressed the A pillar weatherstripping to the corner trim to seal that area. Just bad design there.

Also have original OEM weatherstripping. But thought of replacing the A pillar as I replaced the rebuilt top with an OEM top. And the front lens on the OEM top doesn't dig down as far into the A pillar weatherstripping. And so there is a 1/2" wide ridge impression running in the A pillar weatherstripping under the front lip of the top. So with the OEM top bolted down, there is this 4-5mm gap under the metal lip.

I gave it a quick wash after the install and no leaks so far. I used just a thin layer of weatherstrip adhesive in the A pillar top corners, they fit very tight into the corners, otherwise I used no adhesive anywhere else. I used various size gasket scrappers and pics to remove and clean all the old stuff out of the channels (that's key). My B pillar to glass is tight as well no glass adjusting necessary. I was surprised too cause I read on here alot of issue with doing this job so I was prepared for the worst, but it actually went very smooth. Maybe I'm just a lucky one, thanks guys

A pillar. And the closed cell foam under the weatherstrip retainers.
