    I just looked up a 1991 Dakota with a 3.9 V6 and a 5.2 V8 with an A500 (42rh) and they show the same flexplate ATP Z196 . I think you're all set.

      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

      So there was a u shape machined into the bellhousing on my 42RH for the hall effect pickup that gets triggered by the old flexplate I dont intend to use. What did everybody do to theirs. I figure tight welding a piece will warp things a bit. What about filling it in with JB weld just to get rid of the cut out? What has everybody else done. I know JB in there wont have a bunch of strength. It was more for aesthetics to get rid of the cut out.
