Fork Rod Grinding On Starter

Hi All.

I have a 72 Duster, 340, 4-spd.

When I depress the clutch, the fork rod grinds hard against the starter motor. It's so bad that the spring washer connecting the fork rod is now totally shredded and gets caught on the side of the starter - preventing the clutch pedal from returning.

The car has Doug's Headers and a mini starter.

There's literally about 1/2" between the header pipe and the starter motor.

Has anybody else dealt with this problem with these headers (Doug's)?

I'll get pictures and post them.

Thanks,

Paul
