I have a pretty old Ti-Car Model LS10 220 volt table saw. Had a small accident and it fell off a skid we keep it on at work and smashed the cast iron fence slide. This part housed the lock down and held the fence. Any ideas of where I can get parts for this? I have done web searches for the company or old parts and can't seem to find anywhere to get them. It might be just too old or such an off brand that there aren't parts anywhere to be had.
