Speedbleeders

[Mark Sinclair <msinclair@dis-inc.com>]

I'm trying to order some speedbleeders but keeps getting the runaround from 
Jegs, Summit & Russell - each referring me to the other. Does anyone have 
the part number for these or know the thread size for a Spitfire.
I've heard good things about these but getting hold of some is proving to 
be a bit difficult. I'd like to avoid removing a bleeder from the car if 
possible.

Also - has anyone used these for bleeding the clutch?

Thanks
