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:

However, the master cylinder itself is a simple Ford unit.  Although you 
might not be able to cross-reference it directly, you can buy a replacement at any 
auto parts store.  You just need to know the bore diameter.  

I believe a Bendix 10779 is a 1 1/8 inch bore, set up for disc/disc 
operation.  There are many other units which externally look the same, but differ 
internally because they are set up for disc/drum.

So, you could ask for that; it would probably work great.  Or, you could go 
with a larger or smaller bore depending on what your existing unit is, and 
whether you want to change brake operation any (larger bore will give a firmer 
pedal with less pedal movement for a given amount of pressure, but higher effort).

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

>>>Yes--and mine is hooked up backwards. :<(

The larger reservoir (which is normally the rearmost reservoir on the master 
cylinder) goes to the front brakes, because normally the front brakes are 
larger and thus have a greater fluid demand.
