I have been looking for a power brake booster to fit an E-body with a hemi. The aftermarket seems to only sell boosters that bolt to master cylinders with two bolts, but I need one for four. Does anyone know of one that will replace an OEM booster? Will a B-body hemi booster work in an E-body? Anything else interchange? I have a new master cylinder that came the my brake kit and hate to have to get another one. If it comes to it, I guess I will have to.
