Squrel;
Actually there were four companies involved with masts involved with the H 26 and 260. First Z Spar bought out Kenyon Isomat but after a short while, Z Spar left the U.S never to return under that name while Kenyon Isomat name was gone. Not going into why but it was a fiasco. The folks at Kenyon Isomat reinvented into Charleston Spar at the same location in Charlotte, NC but later becoming Sparcraft. Parts for Charleston Spar suggesting you go to Rig Rite. Z Spar reinvented itself into U. S. Spars in the old facility in near Gainesville, Florida. As for Dwyer, separate company all together. So if your mast is a Z Spar, first go to the forum site or secondly go to U.S. Spars but this forum store knows what parts you would need for your specific mast. Same with Dwyer Mast. However; if your mast is Charleston Spar/Keyon Isomat, go to Rig Rite as I think the forum store cannot get those parts. Hope this helps you. So it does matter what you do have as the rigging is different which can be costly. As for the early rigging for Hunter, it was made by Seco South near Tampa Florida.
Shipping going across the border can be costly but also a lot depends on the mileage as well as the mast is shipped as one unit.
