So pic 1 and 2 show the insulator holes on the wrong side of the bracket. Thats one bracket. Pic 3 shows the other bracket and the tab is in the wrong spot.
Both were from the 273 motor.
I took the bracket from pic 1 and 2 and moved it to the passenger side, but there is no hole for the front bottom position in the bracket.
I see I put it on the wrong side of the boss, but same net effect.
