Where to purchase replacement binding post for inverter

System

Hello

Keeping a long story short, A few years ago we damaged a 3000 Xantrax Prowattz inverter. One of the binding posts was damaged when the unit was removed from a tight spot. Now many years later I want to fix it but have not been able to find if the binding post is a "generic part"

here is a picture of the back of the inverter.

The unit is in Costa Rica, forget about finding parts here. I live in Canada, in Montreal I found a local Xantrax dealer who has the part but is asking 40$. That sounds expensive to me ? I sent a replacmenet inverter many years ago, an in-store brand and it has the same connector, which has me speculating that this part should be mass produced and easy to purchase on-line.

If 40$ is the "market" price then I'll purchase it from the local store in Canada and bring it with me to Costa Rica on my next vaction.

I'm not concerned about using an OEM part as this is a backup unit.

thank you for any suggestion you might have.
