WTB: MTX Thunderform Subwoofer Box NFTRC05C10-T45 for 2nd gen Crew Cab

I have hear that once upon a time MTX sold a Thunderform Subwoofer enclosure for our 2nd gen crew cab trucks. I'd like to buy one if anyone has one. Seems like a sweet deal for someone that doesn't need the storage space. They were discontinued years ago. SKU: NFTRC05C10-T45.
