I'm sorry, the Granada did not have power brakes, just what I wanted. I may actually be able to mount this one on the firewall, although I haven't decided on that for sure. I really want it under the floor in order to keep the firewall as clean as possible. My only problem now is converting the old 35 I beam axle to the disk brakes. I'm trying to use a 35 front end in the 30. The 35 axle has about a two inch drop and besides, it was free. The spring perches are an inch or two wider so I think, with a reversed eye spring, the drop should be 3-4 inches.
