tailgate belt seal

anyone have or know where I can get a new or like new belt seal that will work on for my 87 Pontiac Safari, I'm talking about the seal that goes along the outside on the bottom edge of the tailgate window. I've been looking for the last couple years when I've had the money but the closest was through Steele rubber and their was a straight seal that they bent the end upwards on causing the seal to ripple so wasn't sure if it would work right or not.

Ah yes, the joys of owning old cars with basically no restoration parts market.

Going to have to find a good used one someplace or get creative with some aftermarket weatherstripping.
