73 Duster Spare Tire Hold down bracket

Immediate need.... My shop is trying to 'fix' a badly rusted spare tire hold-down, gas tank strap bracket on a 73 Duster. I would prefer to replace if anybody has one laying around. I did have a suggestion from a member to try AMD. They do in fact make them, but would not sell me just the bracket. They ship installed on a full trunk floor replacement only.

Thanks in advance
Dennis
