We have a low deck 452 in our 70 RR with a Lakewood and a RobbMC starter and it bolts right up. The flywheel is a 143 tooth. There are two sets of holes on the Lakewood, for the 130- and 143 tooth flywheel.

I have been very pleased with the RobbMC starter.

Regardless, your starter should just bolt up. On our car we used just the cap piece shown in the photos someone posted (it supports the nose of the starter) and the correct bolt and that was it.

Tis a puzzle.
