Crabs, thanks a million. It was great information that you furnished.

I want to thank everyone who helped out on this survey. I am attaching the information that I published on the NCRS Technical Discussion Board this afternoon. The response is now 23 1990 ZR1 owners helped out on the survey.

1. Ed, thanks for the response. Your 1990 ZR1 VIN#1990, build date of April
1990 is the last 1990 ZR1 that I have found with Guide Glass Headlamps.

The first 1990 ZR1 that I found with Plastic Wagner Headlamps is VIN # 2124, (NOW VIN 1996)
no build date available. The next response that I have with Wagner Plastic
on the 1990 ZR1 was VIN # 2282 with a build date of May 1990.

I had twenty responses from the 1990 ZR1 owners alone.

Your time and effort is greatly appreciated and the change over period is
pretty narrowly defined with your help and the rest of the individuals who
took time to respond.

The non ZR1's are a different story. The change over was sometime in Feb/May
1992 when the change over from Glass to Plastic was first noted. The last
Glass Headlamp response that I had was in February 1992. The next three
responses that I had were for Plastic Headlamps during May 1992 and they
were Sylvania Headlamps. The first response I had for a Wagner Plastic
Headlamp was late in the 1992 model year.

In the responses that I received, Headlamps after the 1992 model year were
Wagner Plastic for ALL Corvettes, except for a response that I received
stating the owner had Glass Headlamps in late 1994. No explanation for this
finding.
So anyone with a 1992 LT1 who wants to chime in with their responses,
especially in the change over period. please help us out.
