I know of a 601HD that was changed over to spring gear. The owner is very happy with the change. The conversion was done at Quality Sport Planes in Cloverdale CA.
I presume the factory has instructions, but don't know for sure.
The owner is Bill Massey, currently living in Alturas, CA. He has a profile on this site. Try friending him. I have known him for years and believe he would help you with information. If you are unable to make contact let me know and I will email him directly for you.
