Does anyone know how to put a new starter in a mustang, I think this can solve my problem.

Yes.

Go buy it from here, and follow their instructions:

You won't get the proper conversion kit if you buy it from a parts store, and their price is pretty good to start with. The starter is only held on with two bolts. Getting to the bolts is another matter though.
