Thanks,I've never seen an Aft Controls Kit. That being said I don't think its impossible. The linkage rods could be shortened and re-threaded they are about 4" long. The hardest part would be the fabricating a footpeg mount. The Fwd mounts can be made of straight bar stock because there are no clearance problems for the new bolts that hold the pegs. The new part would have to have a mount platform to mimic the old mount then zig out and zag back to allow clearance for the new mount position bolt heads.
She can reach the ground okay, just not the peg position. We are looking at other seats, but mainly for traveling distances.Try a Mustang or Corbin seat...they get you lower to the ground by at least an inch! It may help with her problem, I had to get rid of mine because it was cramping my legs up..
