A/C convertibles have a brace on the pax side that goes from near the back corner of the radio up to the top right behind the upper dash. Non a/c cars did not have it.

I disagree... My Non A/C convertible has a brace, just going the other way... running from the kick panel air duct to the middle of the cowl. A/C cars do have the brace going from the radio up to the passenger side window/birdcage area. This is because the brace at the kick panel blocks the A/C cars actuator for the MAX a/c air inlet. This is the cable controlled fresh air vent on non-a/c car, so its not an issue. Don't know why they didn't just use the same brace as the A/C car though. Guess they just liked stamping out parts.

I'll try this one. There are two braces on the passenger side for cars with A/C.

Gary,

I took those pics when I did a heater core/stereo job several years ago. The braces were removed and are now "purty" with a nice black paint job. At least I hope they are . I haven't looked at them for some time.

Hi Paul,
I hope things are good with you!
Since my car doesn't have a/c I didn't know much about the a/c car details.
Seeing you pictures made me look at the AIM sheet too and I had NO idea the tunnel reinforcement was so involved!!!!!! Very large and 11 rivets to hold it in place.
That cowl must have really wanted to do some serious shaking to require that involved a fix!
Thanks!
Regards,
Alan

Alan,

Yes, that transmission tunnel is very well reinforced with that steel saddle. Something must have happened in the early C3 convertible production for GM to go to those measures. But I do not know what!

Yes, things are OK here. Very strange weather from 14*F last week to 65*F today. And back to 28*F tonight. My natural gas furnace furnace was recalled a month ago for defects in the secondary heat exchanger. But the new one is in before the bitterly cold temps hit. Thank goodness for 10-year warranties! And it works well for which I am happy.

Hi Paul,
I think the early cars earned the name Flexible Fliers for a reason!!!!
I'm old enough to remember there being 2 actual Flexible Fliers in the garage waiting for snow… a full sized one for my older brother and a short one for me.
It's hard to believe how long ago that was. If only I STILL didn't know what I didn't know then! Boy, life was simple and good.
Glad your heating system has been taken care of.
Regards,
Alan

I have never heard the term "Flexible Fliers"! But I have never owned an early C3.

Heating. Not too many years ago when I had a consulting business I had an appointment downtown. The windchill was -40*F/-40*C. That is where the two scales come together. In that kind of weather you can't fool about with a bad furnace.

Hi Paul,
Yes, a popular brand of sled was Flexible Flier.
It had a 'bar' across the front that actually curved the front of the rails slightly when you tugged or pushed on it so you could steer the sled a bit.
The cars started being referred to by that name for other not so intriguing reasons!
Regards,
Alan

OK, I get it. I had one when I lived in the Yukon many moons ago. But I guess I am away off topic.

I don't feel much flex in the 1974 but I don't push it very hard. In fact after I installed a Gary R. blue-printed steering box and re-did the rear with a VBP composite spring (along with a good alignment) this car is incredibly stable. I suppose the only time I noticed any flex was when the hardtop was on. It does have all the mounting hardware but did creak and groan a bit despite new weatherstripping. But no harm done to the rear deck.

Back to the originally scheduled program!

After 40 or so years they will have some "patina" aka as surface rust. My 1974 is not NCRS material so I did a Krylon black semi-flat spray on them after some fine-grit sanding. Good for another 40 years. I am not.

I haven't seen those braces in the various catalogues. I would imagine that you will have to contact Corvette boneyards.
