tr6060 to LA bellhousing

Hello !!

need put a tr-6060 (t56-magnum) transmission behind a LA-mopar (418ci strocker)

QuickTime sell one for T56 no T56-Magnum.
MP sell the P5155286 but have the starter inte passanger side, I think it interferes with the oil filter adapter. Anyone tried it?

I have an eraly A-body with LA-engine and TTI headers.

so I was inquiring and measuring I'm going to have to modify a OEM bellhousing, cut... shorten and weld an adapter plate.

Any advice or suggestions?
