A PCM tray out of a 99/00 and possibly other year blazers will fit GP's, but only for 98-03, due to the size of a 97 GP PCM.
Thanks I'm planning on going to the junkyard to look for a 99 blazer because the one closest to me is pull it yourself. where exactly does the tray sit?
You need to buy one off of a 99+ gp. I'm trying to find one for myself, look at junkyards if u have some locally. Or look for people parting otu their cars.
