Folks, you will have to excuse my in complete message on Glass vs Plastic Headlamps. I posted the entire message to a reply about this issue to an individual thread and not the general forum.

I have conducted a survey concerning the ZR1 Glass vs Plastic Headlamp issue.

I will repeat it here so that you do not have to switch over.

I have conducted a survey and determined that the initial Headlamp on the 1990 ZR1 was Glass until approximately VIN # 1964/1990 in 1990. They had a build date of March/April. The first Plastic Wagner Headlamp I discovered was on a 1990 ZR1 VIN # 2320 with a build date of May 1990.

I am trying to narrow the change over period and would be interested in hearing from any 1990 ZR1 owner. What I would need is the VIN# or the Build Date and if you have Glass or Wagner Plastic Headlamps.

I have conducted this same survey on the NCRS Technical Board and the Corvette Forum so you might have already responded. My results have been forwarded to the NCRS National Team Leader for his review. I will be meeting with him at the NCRS Regional in Kissimmee next week.
Thanks.

Kevin, that would make sense as to the comments of Gordon.
Your VIN falls in with the other ZR1 VIN's that are Glass.
Like I said before, the earliest Wagner Plastic Headlamp was on 1990 VIN # 2320.
Gordon usually has all the right answers. I have gotten some information from him in the past.
Are you the original owner of this ZR1? If you are not, it is possible that they are replacements. However, I would not change anything right now until a definitive judgment on this issue is made. If you do change them, save them.
Once again, I appreciate your time.

swamp,
I'm not the original owner of the car but the car has been in the family since 1999. I have no plans to change anything even if it's "definitive". I respect what the NCRS does but I don't care that much about it for myself.

Kevin, the build date can be found on the inside of the driver's side door jam. There are two white labels on the driver's side door jam. The first label will have the build date on the upper left hand side. It will be a month/year posting. The second smaller label has the tire pressure settings.
Thanks again for your help and enjoy your ZR1. I only wish that I had one.

Been involved with NCRS and restoring Corvettes for a LONG time. It's very dangerous to get caught up in definitive cutoffs on parts transitions. I also worked for GM in multiple plants. Multiple suppliers and old stock play into the manufacturing process as the norm.

You keep the line running at all costs.
