For LA/LB lancer you need to:
1. dent the strut tower to clear the booster.
2. weld nuts on the inside of the bracket, so bolts can come through the original firewall holes.
3. cut 10mm or so off the threaded part of the cleavis, that attaches to brake pedal.
4. bend up some new lines. Or bend the original ones if you don't care how it looks.
5. bend up the bracket (or make a new bracket) that secures the master cylinder to the strut tower.
