42RH / A-500 in a Duster with pictures.
Yep my bolt circle measures 10.0" so I should be good with the ATP Z196. Specs say that one is a 10.0" bolt circle as well. Incidentally that part number goes all the way back to 1967 on 273 and 318. Heres pix of that V6 plate with hall effect trigger ring. Notice all the punched out holes on one side for balancing. I am showing this pic so people know not to use this one on a neutral balance V8
