73 Duster Blower Switch and Heater outer box w/ac needed

It seems the correct 3 prong 45 degree terminal switch for the 73 Duster commands a lot of money. I was looking at other options and just running terminals to like a HS201 or HS203 new style switch. I searched but didnt find anyone posting this issue.

I also could use the front heater portion of the heater box. Mine has broken pieces around it and my car has A/c.

Thanks Brian
