had break in at city dock a few years ago ... damaged one track toward the bulkhead.

dremel/knife cut square end ... got one length of extrusion [~ 6 ft.] used for J105, if I remember right. this was when TPI was still marginally in the J business.

somewhere there is a post on this site.

butted up the new piece to the old piece ... now three years later no problem ... I'm thinking taking the cover off is just going to get to be a real hassle.

I now have spare piece ... but that's staying in my inventory.

basically just a pvc extrusion.
