66 273 Triple Crank Pulleys & Power Steering Pump Bracket?

I'm doing a Slant to 273 Swap.

What other engines can I use the crank pulleys from?

I have a single crank pulley that came with the engine, and I need to add two more for the pulleys for A/C and the power Steering pump

What other engines can I get a power steering pump bracket and pump from?

Thanks
