i have a 10" clutch with a Light Duty 3 speed in my f1. we put in new disk, PP, throw out bearing, pilot, on a resurfaced flywheel. the clutch wouldn't engage, even with clevis adjusted all the way out. we ended up welding up an extension to the rod that threads into the clevis to get the clutch to disengage. since i'm driving it 400 miles, wearing it in, i have adjusted it back in a few turns of the clevis. our clutch set was "new" ordered through Early Ford V-8 (prob from china?).
