Default C4 Windshield Replacement

All,

I need to replace my windshield. A local glass shop is willing to do it but I need to source the weather stripping. Is it available from GM? Where can I find it? Any other things I should do at the same time? Maybe the header piece that goes down to the doors?

Thanks,

Mike

Default Is this it?

I found this on Ecklers. It appears to fit most C4's. For some reason they do not appear to have 85 and 88.

My weatherstripping under my windshield looks terrible.... Cracked and ugly.

That's the metal edging around windshield. You don't need that for replacement

I'd just like to insert a word of caution here. Doing a C4 windshield is not for the faint of heart.

It's something of a major project. Everything around the WS needs to be removed. Interior trim, surrounds, retainers and the wipers. The weatherstrip is of course tossed. The surrounds need to be matched to the new WS so that they fit flush to the glass with little or no gap. BTW those pieces are almost completely unavailable and are very expensive so you need to go easy removing them. Everything needs to be sealed up and replaced with new weatherstrip. The door glass needs to be checked for the seal to the weatherstrip, that's probably going to be OK but needs to be checked. Put on new anti-chip trim along the bottom of the WS. Interior trim is the replaced and that's it!

So I'd just bear in mind all that when picking a glass shop, they need to know what you/they are getting into. Best of luck, I'm sure it'l all be OK.

The shop is a local one and has done c4's in the past. Where can I source all the items? I know I need the A pillar W/S...what are you talking about when you say anti-chip? That black little u channel shaped plastic? I'm lost here.

It's not plastic. It's metal and doesn't need to be replaced. The installer will just swap to new glass
If the installer knows what they are doing, why are you sourcing parts?
You don't need anti chip trim whatever that is, LOL. The car never had it
Only thing that needs to be replaced is the A Pillar weatherstripping

Yep, slides onto the bottom edge of the WS. A lot of C4s are missing it - fallen off or dried up and cracked. You don't have to have it and it can be put on later. It protects the raw edge of the WS from chipping, also the glass edge is sharp. It's available at most of the Corvette vendors, it's cheap. If your shop has done C4s in the past you should;ldn't have any problems.
