Looking for parts for Denesen Vinyl Storm Gliders

Looking for parts for Denesen Vinyl Storm Window purchased in 1984. Looking for the ( spring loaded pins ) Also screen bracket, same window.

I need the locking pins that side up & down. These are sliding windows. The pins are rectangle in shape about 4' long 1/4" thick 1/2 wide aprox. The screen brackets go in the middle on the sides to hold screen in place

Thanks, Dan
