Has anyone taken the seat tracks completely apart? I want to take them apart and clean/repaint. I have the tracks off the seat, but I want to take the runners apart prior to sandblasting/painting. Since there appear to be a couple of ball bearings inside the track, sandblasting without disassembly would not seem to be a good thing. I can see that I need to drill out a couple of stamped spots, but am wondering what anyone may have done to put them back together. Dave S.
