Don,t bother with the spanish gripper air boxes, poor replica , i have 2 of them not even worth cutting apart to try to fix them.
I would be interested in 1 if they were GOOD repo,s.
Regards Nigel Munday Australia.
Let me know if any one has 350 gripper air boxes as i also have one with no air box, and need one desperately.
As far as i know i have the only 350 gripper and 250 orange gripper in AUSTRALIA and need a source of parts.
All the best nigel Munday.
