Manual to power brake swap

glad to help,you will have to drill support bracket holes to the fire wall and inner fender. The firewall bracket used a spacer that was pretty much like a stack of washers. The short bracket goes to the inner fender and the long one is for the firewall. Do you know if that booster is correct for what brakes you have? There is a difference between the drum and disc boosters. The disc booster has dual diaphrams (pic),the drum has one. They are very simple to take apart.
