Someone school me on 73 Duster rear bumper.

The ‘73 Duster rear bumpers are basically the same as the ‘70-72, they’re non-shock mount. They should mount up the same way, with the same gap. A 70-72 bumper should bolt straight on.
Thanks 72bluNblu,

So a 70-72 bumper should fit flush, on a 74 without gaps using 70-72 brackets?
