Thanks for the posts about the pins, and yes, I have the same tracks/pins as the original lifts. My intended inquiry is to find alternative, redesigned, creative ideas that others may have actually built. In other words reinventing a better lifting system.
Perhaps the original design works as intended, and was fishing just in case someone built a better mouse trap.
I am at the stage of having the top pop up skirt made. Hopefully, I can find a local vendor at a reasonable price to sew it.
