Inner one is optional.  Just depends on if yours is munched.  Wiggle the
shaft a bit and check for slop before you tear it down.

New one will not come with bushing or seal.

Thanks! Do i replace the inner bushing as well?
Do you know if the fork will come with the seal and bushing? I am going
to buy AC Delco parts if I can find the part numbers.

You need a semi special tool to do it (or you might be able to fake it).

Roughly: you remove the release arm.
Pry out the seal.
The bushing gets knocked in (here's where the tool comes into play).
Shaft slips up, then out.

New shaft goes in, new bushing goes in, new seal.

Tada!  Done.

Finally got everything broken down last night. Findings:
one for finger broken off. The other fork finger bent backwards.
Clutch and PP actually look OK. Inner bushing fairly siezed up, TOB
looks ugly.
Now for the question:
How do I change the fork? Do I need to solder it off, athen back on, or
weld it, or what?
I can't see a way to remove the fork (it was dark though)

Anything going on here? Don't tell me that the Fiero group is dying...
I haven't finished restoring my 84 Sport yet! Don't go!!!

Clutch is not disengaging, and I am pulling the engine this weekend and
getting it out.
What else do I need to replace whilst I am in there? I have the steel
pedal, I have welded the small cracks in the clutch arm, I am going to
try and find new fork shaft seal. Anything else? 64K miles, runs
fnatatstic.
