No it was off from day one. It actually could be about 1 1/2 longer. I read somewhere"dont know where now" that there was a short rod and a long rod. I may just add to it with some 1/2 round stock.azranger, was your setup correct when you purchased or has it always been off? Guide rod too short, guess you could cut the sleeve a bit to compensate, too long, just paint a ring on the guide rod to indicate level.
mangus, sounds interesting. will be waiting to see the completed project.
