HI, the Springs do need replaceing, Walter from , I believe, NY, has bought a whole bunch of proper springs. He and Bob Lavean have A-10's. This winter, I will start my Mibo A-10, and will also be looking for springs.
Do relize that Mibo has changed the supplier of the struts, i guess when the new struts arrive, they will not need the replacement springs. But we with the older struts , do need replacement.
Maybe Walter will chime in.
