On my last FWB I fixed with about 3x4" 1/8" plate and weldbond. It was winter did not hold so I roughed up surfaces again and reglued, and then drilled in 2 heavy sheet metal screws. So screws held better than glue. Held for 14 years. Still is by all accounts of new owner.
On my '88 Monte I just dremeled contact grooves in a very heavy washer and the frame and epoxied. It's holding after 16 years.
The welded approach likely lots faster, but welder costs money . And did not know how to get car to a shop to do it without the arms connected.
To center I noticed equal mushrooming both ends so just centered in the slot. For washer gauge just find some "very thick". lol
