be prepared to replace the masttrack and the related fittings. It might
be the easiest solution!
good luck.

I am trying to find and purchase about 14' of T-track as shown in the
attached photo. It accepts a 1 1/4" car. It is an aluminum extrusion, curves
around the face of the mast and is riveted to the mast. I am told it is no
longer produced. It came on the older Cheoy Lees' ( 79-80). Contact
with prices, photos or questions. Thanks, Jay
