Hey.... mopedwarehouse.com has the parts you lost, the spring clip will pop out if it dont fit good or is weak, guess you could run about 3 screws around it and would never pop out. Chris at MWH also has the packing it come with... I cut mine in half (noise) and can get 2 cleanings from it... yes they too have to be cleaned out and some holes unstopped in the center part at the end... not a big deal! Doug D
