I understand there are three adjustments for the headlight door: The doors have (3) adjustments 1. Stroke..This is the threaded rod exiting the air motor to the pivot pin (this is NOT used as a limit position) When this is set proporly the head light door will move more up (more than you need)...

Tom - Yes, did try that ploy also. I bought some new stuff that freezes the bolt - will try it soon. CRC makes it. Jon

That was my 1st step last year, I then bought a heavier duty one even though that one worked fine on my other cars. Then went to a long shaft for extra leverage - nothing despite soaking it for weeks with PB Blast and similar products.

Thanks! Yes, the car is 100% stock and I plan to keep it that way. BTW, my '81 is the car featured in Richard Prince's Corvette Restoration Guide 1968 - 1982 due to its originality. There are over 15 pictures of various engine, interior and other parts of the car. I've owned the car since...
