Jim,
here is something simple to look at and try.
Depress your clutch pedal completly.
If it bottoms out on the fire wall adjust the rod on the master cyl out wards until the plunger stops the pedal.
Then adj it back just a tad,so it does not strain the cyl.
I say this because some bdr,s built around this vin.no had a master cyl with a slightly shorter stroke.
On these few cars this adjustment was critical.
Let us know if this helps.
regards
