Quoted from cottonm4:I can take some better pics if anybody needs them.
Thanks for posting these measurements.
My game also arrived to me without these brackets. It's on location and people were really enjoying the gaps between the flippers, forcing them to play on the fly. But it was also a PIA because the ball would sometimes get stuck between the upper flipper and the post and the players would tilt the game trying to free it. Then the game would need to be opened to retrieve the ball. Not ideal for a location game.
Anyway, I used your measurements to cut out some new guides using some thin tin sheeting and regular tin snips that I already had. Worked out great!
I cut out rectangular sections of tin large enough so I could fold them over to make a double-thick piece for each guide.

Then used my vice and a hammer to carefully fold the tin over, and bend it so the bottom edge would act as a mounting plate.

I did mess up a bit in that I misread your measurement on the mounting bracket and ended making my entire bottom piece 0.35" wide, which was really the distance to the center of the hole. However, it worked out okay I simply used some washers to extend my bolt head over the bracket. It is held securely.
