Bird cage rust
When i bought the car, I pulled the lower kick panels, looked under the glove box with a mirror and flashlight and did not see the damage in the middle. I think a easy way to check for birdcage issue's is wash the car before buying, it leaked like a sieve, anyways if anybody has installed the part from zips or know's another vendor, I am all

Thanks guy. I will post some pics later, worst case would be to fabricate the piece, not a easy job, but may be necessary.
I have same rust and will probably fab something up... Mine leaked like a siv too!!!
check the rear door post pillar, mine was shot... You can see it bu simply removing the moldings along the side
Call C&S (ask Tracy for # if you don't have it).. they're local to the shop.. they've had just about everything I've ever needing for my project..
I also use long island (licorvette.com) quite a bit - they have had everything i've ever needed in stock and ships quick..
Mikey, I have bad news to go along with yours. At least you will be driving yours with the LS Motor WAY before mine.



The last picture, we have already cut out the inner lower windshield frame, My initial plan was to bond new metal to the approx 3/8 lip I left, but with the amount of the rust showing on the inner part that bonds to the fiberglass firewall, I am going to replace the entire lower structure.
I hope everybody's weekend was better than mine, but need to dig in and go after it, the car is almost as old as me, and I am not original either

Mikey- so of us are planning on a test/tune at Bradenton on 8/22 from 10-2, any interest if you are in town?
I'm all in for a test and tune, you know what needs to be tuned! But that's going to be up to somebody else to quit lying to me and do their part of the job the right way and without rushing! we'll see how this week goes since the last 2 were wasted..
keep me posted on your project there..

You are going to replace both inner and outer lower windshield frames, are at least the inner and remove the cowl fiberglass covering the outer to see if it needs repairs or replacing also?
From your picture, I can see areas where rust is starting to bulge fiberglass away from it, and can tell it at least needs fiberglass removed and metal cleaned and treated.
I started running my fingers over fiberglass around windshield when looking at cars couple of years ago. If I feel slightest bulge in fiberglass, I know there is a rust problem that needs to be addressed. Problem is there can still be a rust problem on outer frame you can't see are feel unless stainless is removed.
On coupes I run my fingers over where fiberglass bonds to birdcage to check for bulging areas.
Got a coupe in work now that I knew outer windshield frame needed right outer WS post replaced and all the rest of outer windshield frame treated for rust where fiberglass had separated from it. Could feel ever place rust was problem. What I missed was both door sills and door lock pillars needed replacing too. Couldn't see those at time. But did when body was pulled off frame. Good thing, was all the parts needed to repair birdcage were available.

My car has similar problems.
Mikey, I tried C&S, they would have to locate a vendor that carries them.
Will follow up with some more pics as progress begins.
The front clip bonds to bonding strips which are riveted to the frame. The long, lower bonding strip is also bedded in sealant to the bottom of the frame. This is what starts most of them leaking, the sealant dries up and cracks which allows water to get into the bonding strip. This strip holds water which eventually rots out the frame. The dozens of spot welds that holds the frame to the door pillar post are also hiding under the fiberglass of the front clip as well. you have to remove the clip, drill out all the spot welds, remove the frame, drill out the rivets of the bonding strip, and rivet the bonding strip back on the new frame. When you install the bonding strip on the new frame, bed the frame into the strip with solid urethane sealant until it squeezes out over the entire length, before riveting it back on. This will assure a water-tight seal between the frame and the bonding strip, and the urethane will not dry out and crack like the crap that they used originally. After the frame is spot welded back in place, you can bond the front clip back on the car.
It is not readily apparent how this is constructed by looking at it when assembled, but as it comes apart, you will see that there is no real way to do this repair with the front clip on the car. Drop me an Email, and I will chase up some pics to send you documenting the process. It is a miserable job to replace the frame, but it can be done. Last time I did one the repro parts were not available yet, so I had to repair my original. It will be a whole lot easier with new parts, but it ain't a quick and easy job! Here is basically where you have to get to to replace the frame:

The part arrived yesterday afternoon, rough mock up has been done, Peter will do the patch needed on the left side, then weld/bond the new piece in, I have some pics, but having some technical glitch to get to load. Will follow up with that.
Gary at Cardonia Classics was great, part arrived next day (needed it asap, remember, this is my daily driver) Thanks for the tip and phone number on him again Count and John Z.
Sure hope this goes the way I think it could go, some of the others may do this procedure if the nose does not have to come off. Much better repair rather than trying to piece and patch many, many places.
