starter fitment question

A slant and LA/Magnum/BB starter are interchangeable. Longer ones were the high torque. The late model MagnumV6/V8 starters were the ones to stick in early mopars, smaller and more power. I didn't realize they were the same as a 5.7 but an A engine trans will bolt up to a 5.7 and the starter does bolt to the trans....
