Late Auto Crank to early Manual Spigot

Then just buy a bushing, they all are the same input pilot diameter on 3/4 spds.
Some cranks arent drilled deep enough, in that case you can either 'try' to drill it deeper or lop about an inch off the input so that only about 3/4" to 7/8" of it is riding in the bushing . I have a couple like that. Some did it for the crate motors as well, shallow pilot. There is a bearing style you can use that sits in the crank register as well. Your mopar dealer can get it for you for about 20 bucks
