First they are not double dins, they are GM or din and a halfs, thats why you wont find any on crutchfield, I can sell you mine, I never used it, ripped that bitch out the day it came in on the truck, just has a woodgrand piece on it, I dont think it was a combo tho, I could be wrong, its for a 99 GLS model, but no souped up sterio (I knew I was ripping it all out anyway)
