I also revamped my clutch linkage. For the lower pushrod I used a cyl head bolt, a heim at the cross bar end and a lug nut for adjustment at the fork. I think the head bolt was from a jeep six cyl and I used a ford half inch lug nut. Cant remember if I cut new threads or if I used a bolt with a stud on top. You do have to enlarge the hole in the fork. I think I ground off the pin on the cross bar and drilled the correct size for the heim bolt.
