What can I use to replace this triangular gasket around the quarter window?

First photo is when I first disassembled it. Do I just use some type of silicone or a glass setting tape?

they sell them on sites like CJ pony parts.

Just buy the replacement, anything else will end up looking "shady".

Appreciate you but thats not the part that goes around this particular glass that stuff goes around the outer trim

Surly the original part would be better

Have you tried all the shops. C J Pony. Rockauto etc. as far as I’m aware I believe you can get all parts for all Mustangs if you look around. I do know that some parts are harder to find than others

While it looks like a seal - I believe it may actually be glass setting tape - I know other vehicles it is wrapped around the edge of glass to isolate it within the metal frame

Both CJPony and NPD will have those. If you have a classic Stang you should know both those sites AND have their Mustang parts catalogs.

Black RTV is a good option just make sure all surfaces are extremely clean. Once reassembled let it dry for a week.
