Thanks for the identification of the Mystery slave!! That sort of makes sense. Maybe I'll go see if Napa has one I can compare it against.
I agree on the toyota fork. It needs the extension to clear the bell housing.
The problem isn't actually with the clutch engaging, but rather the ammount you have to push the pedal to make it engage and disengage. The clutch disengages right next to the floorboard and is fully engaged with your foot way off the floor to the point that my knee just about touches the steering wheel. I don't think there is anything else left to adjust because with the current master/slave setup it requires that travel.
So basically I think we have a mismatched master slave combo, and I would like to go back to the toyota slave, and Spector has a mount that will do it. HOWEVER, the plot thickens. Now we have the Mystery bastardized bell housing to contend with!

Not only does it have the Mystery mount welded to it, but it appears to be cut away in a manner such as to accomidate the starter. I think the part that was cut away had the mounting points for the Spector bracket.
Additionally, we have a mystery clutch, flywheel, Pressure plate, adaptor, and throw out bearing to contend with. Hmmm...
Looks like we might need a new bell housing to accomidate the slave mount, but I think it has to be a specific model to fit in the FJ60 channel, and while we're at it we can try to identify the interior mystery components.
I've read all sorts of contradictory things on the internet about which components are compatable and which aren't, and I would love for anyone to tell me a complete list of components that they are running that will make this setup work.
What Truck?
What engine?
What trans?
Adaptor type?
Adaptor thickness?
Bell housing?
Master?
Slave?
Slave mount, Spector?
Clutch?
Flywheel?
Pressure plate?
Fork?
I really appreciate all the help! This forum's really great. It seems there are lots of knowledgable people. Now I'm starting to want an fj40... If only we weren't limited for parking. Can you mount an infant seat in a 40? Nevermind, that's for another forum.
Thanks,
Christine
