Clutch problems

On my 1982 mustang gt with a 4 speed manual I couldn’t get it into gear after I started it, so I adjusted the firewall clutch out and then it worked then the next day it wouldn’t go into gear then I adjusted the fork adjuster (not sure what it’s called) and it worked, and then after about an hour or so it won’t go into gear and it grinds when I try to put it into reverse... if anyone has any clue what can cause this please let me know. Thanks.

I had some similar issues on my car when I was running headers for an automatic on my 5spd I ended having to reroute my clutch cable

that’s really weird. I don’t have on headers I just have the stock exhaust manifold.

Cable worn and stretched (or getting ready to break) can cause it. Also, adding a stiffer aftermarket clutch can cause an old cable to stretch and/or break. Another thing that can happen is the adjustable plastic quadrant can wear out (especially when paired with a stiff aftermarket clutch). 82, iirc, was the first year for the plastic adjustable quadrant. Before that, cable adjustment could be done at the clutch fork. You can purchase aftermarket cables with the adjustable clutch fork end for the 82-93, but the oem cable was non-adjustable. Adjustment for factory clutch/cable setup was made at the quadrant. Since the plastic quadrant was a known weakness, aftermarket introduced the aluminum non-adjustable quadrant and a separate firewall adjuster.

While the cable is typically the culprit, the clutch pressure plate fingers have been known to occasionally wear out... although, the clutch material itself is usually the first to go... which is why pressure plate failure isn't as common.
