Hot Rods 34 Chevy Master question

I am looking for anyone who might have a picture of the rear bumper mounting brackets on the 34 Chevy Master.
I bought a new bumper supposed to fit my master. However none of my bumper brackets seem to fit.
I have 3 bumpers and it may seem stupid but none of the bumper brackets seem to fit. So I either am trying to fit wrong brackets of have lost my mind ( both possible)
A picture, diagram or anything that can show me how they attach to the bumper and mount to the car.
Thank you

There's several sets of '34 Master back bars. Rear mounted spare takes 1 set, 6 wheel another, sedan delivery may also be different. I gave away my '29-'36 parts book or I'd look it up.
