When they come in, I’ll post up some pics and cross my fingers they are right.
Mark a painters stick, center of the bolt holes and measure. The holes are in the frame rail walls, and take 1/2" bolts. The rear hole is generally say 1.4" from the back of the rail, so the forward hole is 5"-7.1" in front of that. If leaf springs, wow, might be 5.3", I can tell you how to modify what's available. I'm only aware of 3 patterns, perhaps there are more, as common brackets have more than one bolt pattern. FWW, the bumper brackets extend approx. 8" behind the frame rails. Technically, I measured everything Also FWW, reproduction brackets aren't very good, and may need to be flattened to sit flush to the bumper.

Do you have leaf springs or coils?
