Who makes this tire rack?

I saw this tire rack on a Cherokee the other day, and am hoping that someone knows who makes it

I'd like to get the tire off the body on my Blazer (and on the Jeep that I hope to get soon) and put it on something easy to replace if I rack it up.

Thanks

Its not aftermarket, it was a factory option for some years.

Thanks Ray, I've just added it to my must search for at the autowreckers list.

I really hate how Chevy just bolted their version to the weak cab corners. Even though I braced mine there's still some movement there.
