Good morning Nash, First I'll say that a lot of free travel in the clutch (within reason) is good from a wear standpoint. When you run out of free travel and adjustment, your clutch disc is probably wearing thin. Is it safe to assume that the movement in the pedal is smooth, without any binding? Would this happen to be a fresh clutch job, or is this something that has been, or just did happen? If it is fresh, I may be able to talk with you about what happens in the bell housing and such. As for the pedal slop and rattle, I may not be as well versed, but I'm confident there would be some bushings in the pedal assy that would be prone to wear. There is also bound to be a return spring on the linkage for the pedal you may want to take a look at. I'll check back later, or you would be welcome to PM me.
