Thanks Dave,
That service bulletin is what I looked at when making my bracket. I think the height of the booster brackets vs the firewall mount is very little - the pedal rod does look a bit taller than the original in the picture and the angle on the bottom of the booster bracket does make it look higher but like you say it is just a picture. After a bunch of measurements I didn't see any need to raise the unit any higher except for possibly heat issues off the manifold. If that becomes an issue I'll just add a heat shield. Looking at the top of the booster bracket it looks pretty even - maybe an inch? higher where the booster would mount.
Didn't want to change a bunch of things at once so figured if I moved the booster out 1 3/4 the only other change to be made would be to lengthen the pedal rod 1 3/4.
Fits perfectly.........almost 1 1/2 clearance to the valve cover because of the shape of the original booster. I'm sure this would never work with the larger and longer replacement style dual action booster.
Just held on with a few bolts at the moment to verify clearance. Will be adding the evap. box pretty soon and will need to take it back off to make that install easier. It is closer there - only 1/2 inch clearance from the back of the booster to the evap box.
I think I see what you are saying but that bracket you show riveted to the back of the booster is standard on all the external firewall mounted boosters.
