Flywheel questions...

Any more info on this? Were there bosses there to drill and tap or something? I don't remember any on mine, but I don't remember looking either.

I've planned to cut the starter pocket out and relocate it to match a 130T flywheel. I was going to drill a flat plate to match the pattern on 727 bellhousing and then use that to fix the starter pocket location before welding.

Really rather just drill some holes.

Sorry, I miss your question. Lower hole was ok, I just tilted upper part closer and made a new hole. There was enough material, but no specific boss for that. And the starter pocket "nose guide" needed some trimming inside the bell, if I remember right. Which is no problem, cause RAM MP starters bendix gear is supported on its own.
Surely it would be easier to go with 143t with Dakota bell, but I got hemi alu-flywheel so cheap that I went this way.
As a pilot bearing, I was using `90-up mopar pilot bearing sleeve, and just opened the center hole for Toyota bearing, and didnt push it too deep, so the input shaft tip slide good amount in.
