How do I find out which of the two diff blower motors I have?

[Maluco]

I show two different blower motors for my car. One has Aluminum Inlets with a 5" fan diameter and the other has Plastic Inlets with a 4" fan diameter. Will either work?

ck the heater core hose connections at the firewall engine bay drivers side. if aluminum then get the alum one etc. For reference my '88 325is with a 6/88 build date uses alumn core.
