Clutch Fork release rattle

I own a Crown Victoria 5.8l (351W). I installed a T5 tranny from '95
Mustang 5.0l. I should be the 1st 5-speed Crown Vic in Canada lol

I actually have a 50oz flywheel (the one from the 302), while my 351 needs a
28oz flywheel. So, there is a vibration at high RPM. I will receive a new
flywheel next week. I drove my car like that for 3 months, but at low
speeds (below 2000rpm)

After few weeks of driving, my clutch pedal started to rattle when I don't
touch it. If I let my foot on the clutch to put a light pressure, the pedal
stops to rattle. I looked under the car, while car was idling in neutral.
The fork is jumping! Huge rattle. The rattle increases with RPM. Now I
drive very slow letting my foot on the clutch to stop rattles.

What can cause that? All bearings were new, clutch (10.5 in) and pressure
plate were also new. Can that rattle be caused by a loose flywheel? bad
release bearing? I suspect a loose flywheel because of the vibration due
to the wrong flywheel (?) If the flywheel is not in cause, is it safe to
drive my car like that for 1 week before I receive my new flywheel?

Thanks
Jeremie

Let's see... you're getting a new flywheel in a week. Suppose i say it IS a
loose flywheel?

Why take the chance? Find another ride.. even if you have to rent.

It's not caused by a loose flywheel. It's just a
clutch cable out of adjustment, nothing to worry about.

BTW, you did put a pilot bearing in the end of the
crank shaft, didn't you?
