One of them on my 2002 is badly damaged. They're bolted on with a T50, and I was able to get it out with an impact, but I can't find the part number anywhere. The only identifying marks on the good one are "241" on the bottom of the bracket; these are at the back of the cargo area, there's a welded nut under it on the body into which the T50 bolts in. The bolt is usable but the tie-down is wasted; I'd love to buy another, or even a pair and new bolts.

Any idea on a parts search on this?

This is what the usable one looks like.

 

Junkyard or aftermarket one sized close to it. It's a 20-year-old truck so forget about a new identical one.
