I’m a little concerned that getting the springs back on could be a pain.
Actually, the springs can be fully inserted and attached from the bottom side. No need to run a fish wire or worry about the top end coming un-hooked.
Set the top pedal in place over the base plate. Grab one end a spring with needle nose pliers. (the spring should be orientated such that it is extending out from and in line with the jaws) Insert the free end of the spring into one of the spring openings, hook the upper end onto the slot in the pedal, pull the lower end down and clip that end of the spring onto the base. Do the same with the remaining spring and your done.
I too, always thought I had to hook the upper ends all up BEFORE assembly till I had one drop out of place un-noticed. Just picked the spring up off the floor and inserted it as I described above. Very easy, better than trying to keep them all hooked up at once.
