So I think I'm gonna have some decent springage here finally. Using a trimmed 750sx spring.
Wouldn't work with the WDK bracket, but purchased an x-metal style single tube bracket and it looks like it will line up pretty well. Gonna mock up the bracket on the ski tonight to see if the bottom of the spring that over hangs the bracket will need to be cut or not.
The stock pole bolt is a little long for the x-metal bracket, but I'll just space it out with washers or something.
The spring is trimmed on the top right after where it disappears into the pole as seen in the picture. I thought i took a pic of the spring by itself, but can't find it.
Thanks Surfersmurf for the bracket and WolfChild for the spring.
