93 22' open. I plan on installing a bow shade utilizing the bow rail with a couple bolt on rod holder and the t top. When measuring I noticed one of the thru bolts on the bow rail broke off flush with it. Taking of the bow rail to see what i need to repair another bolt broke off loosening the nuts. The stainless bolts looked to be either pressed on or welded on in the manufacturing of the railing. I could not easy out the broke off bolts. Does anyone know how they thru bolts are attached? I have a couple options. #1 Drill out the old broke off bolt and weld in a stainless bolt around the hex head. This option I worry about the alignment and warping the rail with the heat? #2 drill out the old broke bolt, tap the hole. Put some JB weld on stainless all thread and let set. should keep the same angle. worried the jb weld may not hold when tightning down the nuts. Anyone deal with anything similar?
