Have you tried www.theseatshop.com ?

Looks like they have it, maybe a little pricey, but thanks for the link!

the do offer wholesale pricing for business, its about half the cost

Use the seat shop all the time for trucks to replace worn drivers seats. The covers are a good match (after you clean the seat backs). Yes they have better pricing. Compared to a dealers wholesale price they are cheap.

Found an ebay seller that gives a lifetime warranty on the foams. Have one in my personal dodge cummins and works great and was like 90 bucks for the bottom bun

American Cushion Industries
