Question on 77 Door Panals
 

I have a friend that just bought a 77 Chevy short box and his interior is blue. He wants to change it to black. He ordered a LMC catolog and the door panals show that he needs to use his factory inserts. The problem with this is they are blue. He is looking for new black panals complete and all new trim for them as well. It is a factory pwer window set up as well. I know where to find the parts for my 71 but not so on the 77. Any help on where to go to find this would be great. Thanks
