Need advise on non a/c pully's, taking off a/c pump

So I did a v8 swap a few years back and the 74 dart 318 I installed in my 69 dart had a/c so I have been running the car with the a/cc belts running thru the pump. I have issues with the belts squealing a bit at higher rpms.
I need to find out what parts I'll need to get rid of the a/c pump.

The engine is a 74 318 power steering.

Do I need a new bottom pulley?

new brackets for the alternator.

any link on where to buy everything. Thanks
