Is this rust normal...?

Yes the harness goes over the top then down thru the middle. I was going to remove the gages and stuff from the dash pad to re-dye the pad, but it looks a little complicated!

Maybe before the carpet goes in I can move it outside and use the water hose around the windshield frame and in the wiper tray. I DID notice that there seemed to be water collecting in the trim piece that surrounds the rear view mirror mount. And in addition, the ash tray was very rusty (so much so that I replaced it) and the chrome console piece that the ash tray resides in appeared to have been exposed to water over time. The area behind the pillar posts does not seem to be too bad. It's almost as if water was coming in thru the center T-top seals. Since then I had the T-top seals replaced with 'latex' seals and the only thing I noticed was that they squeaked a lot; I guess because of the inherent stickiness of latex against the chrome T-section and the natural body flex during normal driving. It din not squeak before.

T tops can be a problem but I would bet if you removed the stainless trim at the top of the windshield you'd find leaks between the glass and birdcage. Water lays in that area under the trim and rusts through. The factory should have filled that area so water couldn't collect.

I'd give it a water test with a hose and see if this is the case. If you do indeed have a hole, it's not necessarily a huge job to fix providing you've caught it in time. If you plan to keep the car for a while, better to get this resolved before installing new carpets or other interior parts.
Did you take the padding off of the header? If you did, how does it look?
Another source of leaks is a seam at the end of the wiper tub. I found a small gap in mine where a piece of caulk or sealer pulled off. This woudn't cause water to drop around the mirror.

Thanks for the advice: Here's what the back section of pillar posts & header trim and header (?) look like?
The 'header' does not look bad??? Or does it?

If you're getting water dripping from around the rear view mirror mount there's a good chance of a hole in the header on the other side. Not uncommon for cars which spent their lives up north. The header often rusts around the top edge of the windshield. Once a hole has developed water gets into the header (hollow) and travels elsewhere.
I'd give it a water test with a hose and see if this is the case. If you do indeed have a hole, it's not necessarily a huge job to fix providing you've caught it in time. If you plan to keep the car for a while, better to get this resolved before installing new carpets or other interior parts.

Water test may be your best bet to diagnose. Your birdcage may be OK, don't want to create undo alarm. Just sharing the experience I'm having with mine.

I'll remove the T-top chrome finishing and see what's underneath. All the open edges have been sealed with black caulk or rubber sealant, so historically, maybe it has always leaked in that area. What is the best way to reseal it after I get it apart and clean off all the old sealant? Is there a 'sticky' or valuable thread on that subject?

Hey,
Maybe this will inspire you a bit : http://forums.corvetteforum.com/c3-g...c3-1976-a.html
I've done a complete restore of the interior with my dad. It was great and the car looks amazing now.
Enjoy.
When I look at your pictures, all I can say is, take it all apart, remove all the rust and add a coat of ZINC primer. The birdcage metal I've done with Zinc and POR15 myself.
Take care,
Maarten

If you're referring to sealant between the trim parts, I don't think that's factory. Somebody correct me if I'm wrong. I believe it's most often there because some prior owner had a leak and was looking for a cheap way to fix it. This doesn't always work and leaves the root problem unresolved.
Once you have the exterior trim parts off of the header and pillars you'll be able to see some of the windshield frame. Top corners are a common rust area.
I'd do a water test to see if it leaks. If it does, the only way to assess the extent of damage will be to remove the windshield and thoroughly clean the framework.
