73 Blazer Window Regulator/Channel

[manfromeastvan]

I posted this first in the pick-ups section by accident, sorry for the repeat post. I'm trying to replace my window regulator and the channel that attaches the glass to the regulator. I'm having no trouble finding replacement regulators, but I can't seem to find the channel piece anywhere. In most parts catalogs, there is a regulator listed as good for 1973 models, and another regulator for 74-76 models. I'm hesitant to try a 74-76 regulator and channel unless I know that it works....any advice?
