Just an FYI (sorry if it's been already covered many times before). When the front strap on my '95 rotted out, I just made a patch & bolted / welded it back together. I didn't take a photo of the finished product, but you can get the drift.

Hmmmm.....don't know why the photos aren't showing.....

 

When I bought my truck a few years ago, the gas tank was being held up in the rear by a ratcheting strap since the rear gas tank strap had rusted out. I bought two new gas tank straps, sprayed them with undercoating and installed them. No more issues.

 

Yeah, when my rear strap broke, I was able to buy both straps, new, for under 50 bucks, and the parts store had them on the shelf.......
