Thanks for the reply's guys... I went back to the basics and... found the vibration in the fan of all things, swapped that out and... vibration is gone.

but, clutch adjustment is still giving me a bit of a headache.

here's where I'm at:

the 88504 is a ram borg beck 3 finger style. I looked and found out the over center spring was removed by the installer... which I thought was only to be done when using a diaphragm style ?? so I tried putting that back in... but now I'm getting the pedal to the floor condition like a diaphragm...

tried adjustment on the throwout, ram calls for 1/4 inch at the bearing. At the prescribed adjustment, pedal hits the floor... as I work the adjustment out I can get it closer and closer to a point where the over center is in the correct position to pull the pedal back instead of forward but not without having next to zero clearance on the throw out.

What am I missing here ? This is a 4-speed conversion so pedals linkage, rods are all aftermarket.

Can you run a borg and beck style clutch without the over center spring ?
