1971 AC GM Engine Tune-Up Specifications Manual

Got this vintage 1971 AC GM Engine Tune-Up Specifications manual. It's a cool piece of automotive history, perfect for a garage wall or a collector of old Chevy/GM stuff. It's definitely seen some use over the years with some wear on the edges and cover, but the info inside is what matters. Great for anyone working on early 70s classics or just wants some cool vintage decor for the shop.
