hey rafman60, hows it going man.
i cut my rear wheel lip. i used a reciprocating saw.
make sure you use a metal cutting blade, a small one.
tape the area you want to cut, i used blue painters tape
and marked the area off. if you go the grinding way, you
are going to be there for a long time. because the wheel
lip is two ply steel. and hard as hell to grind. believe me i tried.
