are they on the link bars or the axle,i made some tabs and welded them to the top of the link bars,drilled a 1/2 inch holes in them and i use a 1/2 inch grade 8 bolt.works well for me,i am eventuually going to go to power balls but until then im on heim joints.speaking of that...how exactly is that bolt holding te cylinder in??does he have heim joints with the 1/4 inch bolt running through it or is that little bolt running directly into the shat,cuz if it is running into the shaft i wanna know how he got that to thread.smallest bolt that cylinders take is a 1/2 in.
i took this pic to give you a better idea.
