I just put a new Mcleod twin disc clutch in my cuda. No matter where I adjust the clutch on the adjusting rod, it wants to go overcenter. I cant even drive the car, that's how far out the adjustment is. I measured everything with feeler gauges when installing and according to the instruction sheet they were within tolerance. The only way I can get the clutch to not go overcenter is if I have the rod backed off almost the entire way, but then the pedal is about a little past quarter way from the floor when its all the way up. All the linkage is brand new, new z bar and all new bushings too so nothing is worn out. Has anybody else had any problems with these? It has been nothing but a problem since I bought it.

May have to remove the large over-center spring on the pedal assembly. I had to do this on my duster so the clutch had some "feel" to it after I put the Mcleod DD in.
Agreed,if the over center spring is present, it's got to go

Have you adjusted the free-play until the pedal is hard at the top yet? Then back it off till you have about one inch of free-play at the top. After you do that then check your plate departure and install a positive stop so you don't put the fingers into the springs on the disc. If you can't adjust it to zero free-play then something is wrong with your linkage or you need to adjust your spacing on the release bearing Gus

How long are each of the arms on the Z-bar from the outside of the tube to the center of the rod pins?
How long is the throwout bearing release arm from the contact tips to clutch rod adjustment hole?
There are at least 3 different z-bars and clutch forks AND clutch fork pivot shapes for Mopars. It all depends on which ones you have. Identifying them by precise measurements and then running it by Brewers could be enlightening.

I used a piece of 3/8" threaded rod with some nuts and washers.Just mark the spot on the floor or firewall and drill a hole and insert threaded rod, adjust as necessary. Just Google images of "clutch pedal stop" there are many options and some very good images of some better more technical designs than mine. I just try to keep it lightweight and simple and used what I had in the scrap box Gus
