The stock threaded, adjustable clutch linkage piece that goes from the zbar to the clutch fork on my truck seems to be too short because it is out of room to adjust. Is anyone else using something else for this piece? I tried to get a piece of grade 8 all-thread, but noplace has any. I can get a grade 8 bolt and then cut the head off and round it for the pocket in the clutch fork, but there is only like an inch of thread, so again...not much room for adjustment. Any ideas other than 12 bucks at the local NAPA for another stock piece...? Do I need grade 8 or is grade 5 enough???
