If the clutch problem is between the pedal arm and the pushrod, there are two solutions. If the pushrod eyelet isn't all wallered out (ovalized or "egged out"), you can get some 1/2"OD x 7/16"ID brass tubing, and cut off a real short piece to slip in there as the bushing. Then assmble the arm to the pushrod, and put a 7/16" drill stop collar on the end of the "pin" on the arm, to keep it in place. I have both our '95s set up that way and they work great. You'll still have a bunch of the tubing left, so you can cut off more and replace the bushing as needed.
If the pushrod is worn/egged out from metal-on-metal contact, the next fancier option is to cut off the end of the pushrod and install a heim joint. There are people selling kits for it on eBay, but the individual parts are easily had at a well-stocked hardware, for a lot less.
If there's slop in the pivoting action of the pedal shaft itself, that pedal box bushing kit is available at the dealer. Similar to above, if the holes in the pedal box are worn from metal-on-metal, then I'd be looking for a replacement pedal box, at the boneyards or on the classifieds on this and the other truck forums.
Oh, and of course thank you for rescuing a two-tone, and bringing it back to life.
