Where does everyone go to buy parts? Dealer? Autozone? online store like LMC? I have a 2000 S-10 and the previous owner had it painted and the window channel trim was not replaced. (Along with some other trim pieces)Lmc has the window channel trim pieces for $26ea side b4 shipping.

 

I use all the above. I like OEM parts the best and http://www.gmpartscenter.net/ for online factory parts with reasonable prices/shipping. I rarely use LMC as I feel their shipping rates are high. I also search ebay. Locally I use O'Reilly, Advanced, NAPA, Auto Zone and the local chevy dealer. For the window channel trim I would check the link.
