These are my brackets with 32-119 on the rear. The bracket would not go in but I shaved some plastic off inside the 32-119 with my Dremel bit that cuts sideways. Not hard to do.
(Carefully take small amounts off and try on for size as you go.)
Then I added another wood piece for screws to attach in two places.
Just to let you know my adjustments.
The end that's the rear is 1" but it was a bit too big to go in the plastic support .
I hope this helps someone else with the same issue.
