Steve, I would suggest that you make a machined alu bar in the really right angles, and fix the bottom plate end the vertical plate by a with that. Don't go with stainless.
You can do it by your hands (hard work), or by machinery. (I'm also a machinist)
Cut the threads for the bolts by hand. You count how many you'll need, or I'll help you.
You can put shims or epoxy under. I know how the technique to aligne engines by epoxy.
You may want to address me directly for more info.
I'm lucky to be able to relocate my boat to brackish waters soon ;-)
Sakskøbing, Lolland, Denmark.
Send some drawings, please

Dan, that's an excellent drawing! And I get your point strongly. I'm totally in luck that the center of the propeller shaft, at its angle hits nearly exactly at the top of the bed. Unfortunately, the beds are laid in at a 2 degree angle and the propeller shaft is at a 10 degree angle, so the thrust forces are pushing 8 degrees 'upward' on the ways. That's not too much pressure, but it makes me happy the thrust is directly balanced on the bed.
I'd love to do an additional bend (parallel) on the thrust plate. I decided against it for two reasons. First, it can only run a small distance, since I had to cut the part that goes below the ways into a half circle to fit, and second because that piece is relatively cheap so I can replace easily with a more substantial one if actual use demands it. I didn't put bends at the ends (perpendicular) because I felt the bolts would provide sufficient resistance to bending in that direction. But I could certainly be wrong about that!
The boat is fiberglass (balsa wood core), with a fiberglass deck and cockpit. It's stood up well these past 30 years, but it's due for another round of paint, especially some anti-fouling bottom paint... ;-)
