This is both of the original orange spotted 273 brackets I had.
I do have to say, I'm not 100% sure they were ever right. The trans in this car sat a little crooked when I got it but I'm not sure why.
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.
