1972 GTO

What is the correct p/n for the Window Crank?

I have one handle p/n 20037599 which has been on the car since I bought it in 1987 but some sources say that is a Service Replacement handle.

I also have 2 NOS handles p/n 20037597 which look identical to the one in the car. Which is technically OEM?

Also does the Window Crank Spring get installed before the panel is installed?

Thanks
DV
