Thank you so much for taking the time to measure your track. Not sure where that leaves me, as I think the Barton genoa car (a replacement for the Lewmar type 1 original car) only comes in 20, 25, or 32 widths. I do notice that the button release knob of you car is very different from mine, so maybe my tracks are not original. I think I might have to wait until I’m back out on the boat and measure them.
Thanks again for your help
