Thought I should share my experience with two good NOS parts suppliers that Ive dealt with recently finding some of the hard to find GMC COE specific parts.
The first is
Automobile Archives. They are a little slower at getting things out but their prices are pretty darn reasonable as anyone whos bought NOS parts knows how quickly the price can skyrocket. The second is
Collectors Auto Supply. A bit more pricey but being in the same state (and another office in Canada), theyve got parts out to me pretty quick.
Both have a great selection of parts in stock. Thought it was worth mentioning if anyone needs some of those hard to find parts.
