Hey everyone, I never had the chance to work with Merlin, but I think I spoke to Phil for a couple parts recently. I got the "backorder" response but when I called my local shop they said I could get the same parts either same day or within a few days (not months) They might be worth a call. Www.chapmanchevy.com I got my regulator and window gasket from them...and my windows work great (thanks to SBC too)
