Pete,
Stainless screw corrosion to aluminum mast is probably the culprit. Heat the screw with Napa torch until it is ret hot which breaks the corrosion then let it cool a bit and then hit with a impact wrench and proper bit. Generally will do it.

The mast tracking is in place, but I can't break the bottom fastener, in order to install the T-Track. Likely, corrosion b/t the fastener and mast is the issue. Has anyone had any experience - good or bad - using a hammer drill to break the corrosion bond?? thanks. Pete W. C&C30 MKII
