Where can I get that item by itself and not part of a kit?
Or is that the only way it's available.

That is the only way it is available new (you could score it from the junkyard from any F23, F35, or F40 application).
I even called the mfg and offered to buy 100 of just the bleeder, and they said no.

WCF sells a machined bleeder/coupler unit for around $125+ shipping as part of their F40 kits, but using the stock bleeder and my clutch line connector ($45) //www.fiero.nl/forum/Forum1/HTML/094448.html is less expensive and a better overall length to connect to the stock Fiero clutch line.

The cheapest way I have found to get the OEM style bleeder it is here:
