If Mopar denso yes they are the same. Beware cheap copies. The old original monster sized mopar starters i think were made by prestolite. There were 2 types. One was for slant 6, and small block. I believe it was 1.6 hp. The big block one was longer by about an inch and was 1.8 hp. The mopar mini denso i believe is 2.25 hp. All have a similar mating flange , and same bolt pattern.
