My 70 cuda originally came with manual brakes, but the previous owner upgraded to disc brakes using an MP brake booster, I am trying to install what I thought to be the correct brake booster but have run into a problem. The bolts on the booster don't line up with the holes in the fire wall. See the attached pictures. I have what I believe to be the correct booster plate as well, so I can't quite figure out what I'm missing here. CAn anyone shed some light on this situations?
