Re: 67 Z bars and clutch rods, OEM and repop
Here is a Photo of an original 1966 to early 1967 Chevelle Z Bar being GM Part Number 3872895. If you look closely, you will notice the slight bend in the Z Bar arm about 1" inch before the (hole) at the tip of this Z Bar arm where the clutch rod connects to the bell housing fork. This slight bend in both the early and late design allows for better rod alignment. The aftermarket Chevelle Z Bars do not have this slight bend. If you look at the first post photo of the later design Zbar you can see the cease in the metal for this slight bend. Another way to improve alignment / clearance of the Chevelle Z Bar arm especially when you have headers on a 396 is to use a cresent wrench while the Zbar is hookedup (except disconnect the bellhousing rod from the clutch rod with the oil filter removed). Then tighten the cresent wrench down on the very end of the Zbar and move the Zbar arm to the position that bests clears your headers and the engine block. Do not over bend the clutch arm as you may break the welds on the arm. Also, Chevelles with headers that hit or rub the Lower Control Arms can be adjusted for more clearance by buying some heavy duty tie down straps and wrapping them around both headers (and positioned on the top and below the transmission) tightening them together which bend the headers inward and give you the required header clearance. If possible, leave these straps on over night. The Headers should move enough to give you an extra 1/4 to 1/2" inch clearance.
