power window bushing in 69 camaro?

[anarchy99]

It's been a long time since Ive posted on here. I'm trying to finish up my 69 camaro and the windows are being a pain. I searched and searched in rick's online catalogs, year one, etc, but I can't find the part I need. My driver side electric window regulator is popping out of a cracked plastic bushing on the top horizontal bar. I've take pictures as best I can. If someone could post a part number or place to pick up the bushing, I would be deeply in your debt.
