Hey folks I'm out in the bush away from my tractor and can't make the measurements right now.. can anyone tell me the sizes of the pins? I need to order up some heavy tubing the pins go through to mig up a log skidder when I return.. but I can't depend on availability of the steel tubing up here of what I'll need. I'm not sure if the top and bottom attachment points are metric or standard, ugh. I should have measured before I left Thank you for any replies. freeze'
