I have a 1966 Ford F-100 w/ 352 and a three on the tree. I was at our local hot rod car cruise last night when I decided to stop for a stretch break. When I was ready to go again my clutch pedal hit the floor, I thought that the return spring had slipped off the pedal but I was wrong. I got out of the truck and checked to see if I had any fluid or auto parts lying under the truck and I found what looks like a metal crayon. What is it, where does it go, and did I blow my clutch? Please help.
