[DeTomaso] non pantera question

[Rich]

I am going through items I received with my pizza car.  
I have a hard time throwing out any car part even though it is not for the pantera.
I have two EDCO master cylinders that seem to be made of magnesium.
They are very cool looking but I don't know what to do with them..
After searching google without success I thought I would ask the group.
How do you find out what they are for so they can go to the right home?
