'70 Dart 392 Project; what direction?

Hmmmm having some starter issues. Got a starter off of partsgeek listed for a 2005 ram 1500/manual trans. No luck. Hits the side of the block and the top mounting hole is threaded whereas my bellhousing already has a stud there.

Picked a 1999 Ram1500 5.2L starter from autozone. No tapped upper mount hole but definitely hitting the headers.

5.7 starter left, 5.2L starter right
