440 duster starter?

I use a 318 starter from 96 dodge 1500 pu.I had to remove the terminal re-locator and i cut about 1/4 inch off of the main stud and i had to hog the bottom hole just a bit for a good fit.works like a charm.I have a 440 in a 72 duster with in body 1 5/8 headers.I can remove starter with out removing the headers.i just have to unbolt my Manuel box and pit man arm
but o also use motor plate so no need for motor mounts to get in my way.
