Contactor Wiring/Terminal Question

I'm replacing the single pole contactor on my unit (decided to DIY since $604 for $50 worth of parts seemed ridiculous). My problem is that the replacement contactor has two terminals identical to the old one but two that are different - I need help with hooking up the wires to the terminals that are different.

My old one has four screws and all 4 of the wires have the circular endloops so the screw goes inside of them.

The new contactor has two screws on top and two boxes that you have to insert wires into then secure with a screw. What do I need to do to the wires, if anything, to prepare them for inserting into these screwed holes since there isn't a way to hook the loops on a screw end?

This is what the current one looks like:

and two of the ends on the replacement looks like the ones shown here:

Any help with how to modify the wires (or if I just need to clip off the loops and stick in in) would be great!

Thanks in advance.

Those are wire connectors with a set screw and can be used for stranded or solid wire. Cut off the circular loops and carefully strip the wires with a proper wire stripper so you don't lose any strands or nick the wire. Leave enough wire for the set screw to attach to and tighten well.
