I seem to recall there are 2 different throwout arms, maybe 2 different height pivots. If it's a really heavy p. plate, maybe the t/out arm is bent. Maybe the t/out bearing is too short. A buddy of mine with a 70 Mustang, had issues like that, and it was because the flywheel was surfaced too many times, and the f/wheel was too thin. Since it's a scattershield, it is no longer stock, so it might take some experimenting. A couple guys on the forum had removable covers put in the scattershield to gain access to the innards, which might help here.
