Z bar mods for Dougs or TTI headers?
I had to massage the Z-bar a little as it was close to one of the header tubes. Grinded a little off the bottom and put a subtle bend in the rod to clear the tube. Took several tries to get the bend just right. Didn't have to "ding" the header tubes at all.
Placement of the engine and condition of the motor mounts make all the difference.
