I have an early Muncie M20 with the external studs. I cannot seem to make the 1-2 and 3-4 rods work. They hit on the reverse lockout rod. Also the bracket that the reverse lockout yoke attaches to requires an internal mount. Looked into getting new cam levers but they are 5/16 instead of 3/8. Can someone direct me to the correct shift rods and any ideas on my internal external problems.
