Spent a lot of time on picking the location for the booster and master.
The 8" dual booster could squeeze in next to the trans and looked like I could do a fancy bracket to bolt to the original master cyl mount. Just like the kits they sell for the pickups. Just a slightly longer push rod.
Just because you can doesn't mean you should.
It was a game of fractions of an inch and finally realized working on the trans, brakes or anything else in the area would be awful after the cab was on.
You guys with 47 and later with the stock 4 speed will have much better luck. Could probably fit a 9" dual diaphragm and might be able to use the mounting hardware they sell for the pickups. I even considered the peddle kit ($89) that replaces the whole mount with one made to hold a power booster.
Anyway finally decided to mount it further back.
Next most important consideration was where the new access plate in the cab floor would be. Didn't want it to end up in the middle of a seat support.
Found the perfect location so the access would be under the seat.
Then found if I moved that just an inch (still under the seat) that I could use Randy's push rod without cutting it.
However Randy's super built mounting bracket didn't survive.
I flipped the orientation around to use a straight push from the peddle. Would have lived to use the bell crank just to hold the weight of the push rod, but the trans cross member was in the way.
That also made the booster too high and wouldn't clear the floor.
So had to cut it up and relocate things.
These pics show what I ended up with. Think it is going to work great. Bracket is just tack welded until I finish up the peddle connections.
Removed the rear eye on the push rod and will put a thread reducer bushing to connect directly to the booster.
