NHTSA Complaint #11468031 — 1988 CHEVROLET CORVETTE

In June 2020 my mechanic ran a recall check while performing my inspection. It showed 2 outstanding recalls for left and right seat belt retractor failures. I called 3 local Chevy dealers to set up a repair, and no one wanted to touch the vehicle. They all said to call GM. For the next few months I went back and forth with GM to set up repairs. They set up a reference number-9-6244952226. In a nutshell, they finally advised that they only repair recalls for a certain amount of time and I was out of luck because they no longer had the equipment in stock for repairs. I questioned why not just remove the 1988 seat belt retractors and retrofit retractors from a later model. They did not see my reasoning. I did not pursue this in 2021 due to covid, but I am driving the vehicle now and would like to make it safe. Can you help me? The recall numbers are N910058 and N910059. Thank you.
