Well after a good bit of research I finally figured out what I need is starter bracket part number 0317328, which also goes by 0126050 0126256 (and sometimes without the leading 0). And starter motor 0385401.
I do enough of my own auto work that I can grab a spare solenoid and wires out of my hoard and a new battery (or just borrow a car battery from a lesser driven car as needed) and be set.
What absolutely blows my mind is that I can get the starter motor new for under $55, but the bracket is 4x as expensive USED! (New is even worse price gouging) It's just one piece of metal that any schmoe could cast reproductions of or machine the equivalent of if they had an original for reference...I'd guess it's aluminum (probably costs them under $10 a pop to make), but with the prices I'm seeing I wonder if it's some gold alloy.
