if i did take the od off the rotor, whats the worst that can happen...would it make them out of balance or what?View attachment 1715611736 View attachment 1715611737 that 3/8 wide strip is what they call the od its about .005 thick and was told by the blower guys to have it machined off.. would not hurt it at all.

The worst that could happen is you trash a good blower. The best that could happen is you loose all of the necessary clearance and turn it in to a big heat pump that makes no boost. They’re pretty simple machines, you could take it apart yourself and check everything. If not I suggest finding a different shop and getting a second opinion.
