So I ordered a whack of parts from Pinball Life, including a new lockdown bar for my Monopoly.
It turns out that they incorrectly indicated that this lockdown bar -- https://www.pinballlife.com/mm5/merchant.mvc?Screen=PROD&Product_Code=500-5757-02-00 -- worked with Monopoly so I bought it.
After some very prompt back-and-forth I was directed to the right bar: https://www.pinballlife.com/sternsegadata-east-black-front-molding-lockdown-bar-no-tournament-button-hole.html
I just received a call telling me that they were sending me the right bar free of charge. Further, to not send the incorrect bar back as it was too complex to do the international return.
I don't need the bar so I'll be selling it on Pinside and donating the money to Project Pinball. Even better, my employer will match donations so this will be a 2x donation.
This is how you get loyal customers! Kudos!
