I used a portion of a leaf spring from a very old automobile (1920's). I cut it with a hacksaw and cold bent it in a big a** vise using a pipe for leverage. I dressed it down to accept the tail wheel assembly. https://dl.dropboxusercontent.com/u/32133949/IMG_8714.JPG I later replaced the solid 4" wheel with a 6 inch pneumatic wheel from Matco and love it. https://dl.dropboxusercontent.com/u/32133949/IMG_8760.JPG The spring seems to be about right for a KR in the 700 to 750 pound range. A spring slightly too stiff rather than too springy seems the way to go. Any good leaf spring in the 1 3/4" by 1/4" thick range should work. Check out the springs on an old junk golf cart.
