Okay, I solved my problem with hooking up the Wildwood front disks to the Tbird brake plumbing.  Installing a CASCO proportioning valve.  What I am wondering about is how I can improve the effectiveness of the rear drums.  Didn't know if there were any simple modifications I could add.  Larger wheel cylinder etc.  Thanks if advance for any help.  Car will be strictly for the street as a present to my daughter so if there are simple tricks always interested in making it more safe.
