I just bought a 2017 Com PAC Suncat with damaged boom crutch. I hope to replace it with new or used. Any ideas where to start looking or if someone has one to sell.
I'm guessing you mean a boom gallows, the Sun Cats never used a crutch. I've never heard of a third-party source for the gallows, I suspect Com-Pac made them or had them done locally. It's not a part prone to fail.
Show us a photo and we can suggest some repairs.
