[C4] ZR1 Glass

[John M.]

Folks,

A good friend of mine has a ZR1. It's not perfectly stock, but it's in very nice shape and he's thinking of having it judged within the next couple of years. I think that he'd probably Top Flight with some reasonable preparation.

His ZR1 has the original and correct special windshield glass, which is delaminating slightly, as those windshields are wont to do. It's still in pretty good shape, but of course it won't get any better. A vendor is making what is advertised as a one-time run of reproduction glass, which is said to be correct in every way _except_ it will _not_ have the LOF label. He's thinking of purchasing one of these not-inexpensive reproductions as insurance if (when) the delamination on the original windshield becomes significant. Realistically, his interest in this reproduction windshield has _mostly_ to do with potential future judging.

Here's my question:

Should he buy this reproduction windshield or will he get hammered so badly on points because of the missing LOF label that it essentially wouldn't be worth it?

If I were him, my greatest concern would be that the existing windshield would eventually become un-serviceable. At some point, I think it will (whether, or not, that will happen in his lifetime is another question). When it gets to the point of un-serviceability, the lack of the "LOF" on the replacement will seem like a minor problem.

It's always a "crapshoot" in these things when purchasing replacement parts, especially very expensive ones, against future need. I know that "syndrome" all too well. With over 14,000 NOS parts in my collection now, you KNOW what my answer to your question is without me even stating it.

Joe,

I knew I could count on you to weigh in. This may be a stupid question, but will you be at the National Convention this year? I'd love to meet you in person ...

Yes, I hope to be there.

If Joe doesn't show up, we'll know that ALL the lobsters have died.

Well, if I do hear that there's a serious shortage of lobsters at that time or a "red tide" causing the temporary closing of all the clam beds in the area, it will have a DEFINITE impact on my plans. No doubt about that, at all.

Re: [C4] ZR1 Glass

I would think the deduction for condition would be less than that for originality. Since this is a know problem with these windshields I would assume that it should be addressed in the judging manual.

Yes, you're undoubtedly correct. The deduction for condition will, as I understand things, in almost all cases be less than the deduction for a non-original. However, as I say, when the glass becomes un-serviceable (i.e. it is no longer safe to drive with), the consequence of installing a non-original windshield becomes "less of a burden". I'm not suggesting that the reproduction glass be installed now.

Re: [C4] ZR1 Glass

Above is correct for the 89 ZR1s, the 88 ZR1s had a standard C4 windshield.

Which leads to the question. If a car is presented for judging that matches the build sheet, ie all components on the car were installed on the production line does it matter that the car was not avaiable to the general public? Can it be flight judged?

Re: [C4] ZR1 Glass

It is my luck to spend the bucks, get the windshield home, safely store it until "needed" - only to find the spare hood fell over on it when I went to get it!

Tyler it is best to ask that question of the National Judging Chairman.

i under stand the reason for this special glass

was because there was no room with the DOHC engine for a large enough A/C compressor to cool the car so they need a special sun shield on the windshield

Re: [C4] ZR1 Glass

John, original is always better. Mine is the same way and the only time I really notice it is when I am driving directly into the sun.

Re: [C4] ZR1 Glass

Tom,

Thanks for your input Looking forward to seeing you this spring/summer ...

Re: i under stand the reason for this special glas

Clem,

That is my understanding, large glass area, restricted space for a compressor so they added the shield. Some GM vans also have the shield.
