so.....I was wondering how much clearance you guys are ending up with if you opted to shim between tunnel protectors and the tunnel, ( between track lugs and protector)due to the stud clearance issues? Mine has about 1/16" after .187" of shims.I'm concerned about the track lugs rubbing.......an other question for you pros...I had trouble with the rear bolts on the skid frame. I took one side out and then when I tried to take the other side out, the shaft would just spin inside . Is there a trick to stop the shaft from turning? thanks for your help.
