gah, just got done opening the mechbox (one of my biggest fears) and got everything back in ok... (dont worry, i pretty much know what im doing :P)
found out the piston head is not attatched in any way to the actual piston..and to my knowledge, it has to be secured in by a screw...
so whats an easy way to fix this? just replace the screw? or must i order a new piston set
