[DeTomaso] brake questions

[dyogi]

I'm doing a brake upgrade and I have to replace my master cylinder. It's an
aftermarket unit that was mounted with an adapter. I believe that it was a
Hall Pantera unit that came with their Willwood brake set up.  Can anyone
tell me what car this fits for a cross reference?  A picture if it is here:

Also, does it matter which (front or rear) brake line goes to which
reservoir at the master cylinder?

 

Thanks and Aloha,
