Hi Mike
Nice to see the project started, and from the photos that you posted this GS is being restored to better than new condition. I tried to buy that GS when it was in Speedway Automotive in Arizona back in 1989 but the owner said it was not for sale ! I may still have the photos of it sitting next to a pile of other Buicks, If I do I will send it to You.
I looked at the list of parts that you need and yes I can help with the project, this is what I have...
65 Dated LR engine and air cleaner.
Posi rear.
Front & Rear bumper.
Grille.
Radio & speeker bezel.
Tailights.
Wheelwell mouldings.
and many other parts, if you can send me a list I can go thru my parts and check off what I can donate.
Sorry I do not have any NOS parts, just used stuff from many years of parting out Specials & Skylarks.. so keep posting those restoration photos, they look great !!
Tony
