I have a 1968 mustang gt coupe and have run into a small problem! I have a 433 stroker based on a 1969 351w block. I am running a toploader and a mcloed 2800 pressure plate and clutch set up also a aluminum flywheel. I purchased a new z-bar and it seems to be flexing or bending both,and I can not keep it adjusted correctly.Pedal gets closer to the floor over short period of time.Is there anyone that makes a heavy duty z-bar for this application or should I just modify what I have? Thanks Jerry

Ive always stffened my stock ones. Welded a piece of 1/4 flat bar on the rigid to the back of the arm. I might be able to get a pic if you need. For a while I was bending the lower rod. So I made new upper and lower rods using bearing rod ends etc.

[zeuss347]

What did you use for rods that the ends went on for the upper and lower? Thanks Jerry

For the lower I used a long grade 8 bolt with the head cut off and rounded then sleeved.

For the lower I used an all thread rod, sleeved.

I can get pics but not sure how clear they will be.

It has been that was for 15 years and 2 diff cars with no probs.

sounds like a plan! Did you gussit the z-bar anywhere or just add the 1/4 flat bar? I can mig the flat bar no prob and as far as the sleeve goes just good thick wall will work. I wander why noone ever made good aftermarket fix for this? Has always been weak spot from day one if using heavier pressure plate? You have been a great help thanks for everything,hope I can return favor some day! Jerry

I didnt gusset just ran the 1/4 flat bar, bent in the same shape as the flat part of the z bar to the back side.

Yes thick wall and male rod ends work. I used rod and females because thats what I had.

Had to reinforce my zbar, same problem, used a triangle 1/4" plate piece between short arm and round tube. 25 years ago
