Can You Find These Discontinued GM Parts?

Can you find these discontinued GM seat cover parts for a 2000 Chevy Blazer with the TrailBlazer appearance package? I have tried dealers, websites, Craig's List, E-Bay, you name it. Some websites show that the parts are available when you type in the part numbers, but when you call, they are out of stock!!! I am very frustrated at this point because I know that a few must be around somewhere on a dusty shelf, I just can't locate them. Here are the part numbers in case any of you experts can find them: 88934577 and 88934574.

Try an e-search for LMC.

If it's not old enough for LMC, Autoanything or even Summitracing are possibilities.

The OEMs are required to keep stock for 10 years after the model goes out of production, so depending on when your seat trim went obsolete, you may or may not find what you are looking for. Have you tried salvage yards?

Can you go to a good auto upholestery shop and have them make what you need?

Thanks for the responses guys. I tried all of your suggestions, but unfortunately, I'm at a dead end. Any other ideas for locating these parts?

For enough money I would sell the seats from MY 2000 Blazer. HAHA
She's got 210000+ miles on her, so does my '97 Blazer. The 97 is in 10 times better condition than the 2000.
