Engine cover, cover. Doghouse cover. 1978-95 Chevy/GMC, G series vans. Blue. Really cool vintage vinyl you can’t get anymore. Looks black in the photos, but it’s dark blue. Lots of holes and a few seams starting to unravel a bit. Pocket elastic is worn out and the top edge seams on both sides of the pocket are starting to split. Could run as or a good pattern for your upholsterer. See photos
