Today I was bashing at the park with my grandson and I broke my Boost rear driveshaft (partnum ECX3011). Every site I have gone to says discontinued or out of stock. Anyone know of a compatible driveshaft from another ECX model or even a non-ECX model that I could use? Maybe I can cut down a longer one to the right size since one side just slips into the other. Any thoughts? Thanks for your help.
