You're in luck, he is close to you in Delta BC, Gary Yorke, Classic and Performance Cars, Unit129-7198 Vantage Way, Telephone 604-940-9633, only person I will let loose on my C-7. Best Corvette Tech I have ever known.
We had a 99 C5 Convertible that we traded for the 2018 and you're right about the finish, wish we had known in 1999 about the PPF but wasn't around then and if it was hardly no one talked about it. I still would talk to Paul and see what his thoughts are on your C5, good luck
We had our 2018 C7 completely wrapped in Langley BC by Empire Performance Group (Paul), he did a good job and didn't mess the job up. Car guys from the Pacific Northwest will only use him. As well as the wrap we also had the car Ceramic coated. Totally happy and he is always there if you need...
I just looked again and go to the museum website, from the SHOP menu chose build sheets, give "em your info, give them $ and you're in business, hope this helps. Rex
Nor did mine, perhaps we should contact GM Canada to see if they assist, I did years ago for my 66 Big Block Coupe and got a lot of information from them and no charge at that time but believe things may have changed since then ( 35 years plus)
From the National Corvette Museum by giving your serial number they are able to access the build sheet information we ordered for our 2019 Z51 Coupe and was very happy with the information we also had it laminated and have forever now.
