Hey, Many thanks for all the help with the radio. I see the trouble. There is quite a difference between how Chevy did it and how the GMC is set up. The diagrams and pictures are very helpful.

Andice, I'll cruse your way one of these days.

My door check experience is the after market replacements are good and bad. I took the parts from the new models that were broken on the originals and used the stock "bar" to make a better than original part that works well. The original ones both had split the inside brackets that screw to the door. The corresponding part in the new ones had been made of thicker metal which is good. I used the new springs and a new heavy cotter key cut and spread as the original to fix them to the plate with the new "bumper" but retained the stock flat piece (bar) that connects the jam to the door which is made of thicker metal (that is good) than the one in the replacements. The part that shows now is all original but the guts inside are all new. It worked well for me!
