Wow, sorry to hear that. I hope the transit company was properly insured.
I would check and see what other masts are the same length as ours. When I needed a new mast for the Santana 20, we found that the mast "blank" was the same as that for a mcgregor 26, which were closer to get. We did have to re tap all of the fittings, but that was not too bad as we had the old mast as a guide.
