New to the forum, but I’ve owned a couple square bodies. I recently bought a 77 gmc 15 High Sierra 4x4 SB. I’m planning on painting the truck but the Service parts Identification has no paint code, all it has is the code for ZY1 for solid paint. I believe my truck is mariner blue but I want to be sure. I attached my SPI. Please help! Thanks square body world
