What starter to use?...Hmm

They made 3 different sizes of starters for mopars, the large old style, a much smaller one from the late 80s I suspect, and a tiny one from the 90s up to the early 2000s in trucks and vans with magnum 3.9/5.2/5.9 motors.

I have the tiny one and it works awesome. And has much more room around it.
