1988 Supra Comp TS6M Restore & Repair

Hi All, I'm looking to sell my boat but I want to restore it a bit to increase the sale price. I am having a hard time finding the parts I'm looking for. Does anyone know where I can find the rear vents and instrument panel? I also have a long scratch in the fiberglass and a chip. Does anyone have any recommendations on a quick and easy way to repair it?

I am not an expert in this area, and I have no experience in working on boats.

Finally, if anyone has any other suggestions for quick and easy fixes to make prior to selling please let me know. Below is a picture of my boat.

It also won't start. Does anyone have any ideas what might be wrong with it
