To any who have done this, am I missing anything? 34 stock axle 34 spring perches A shackles w/ spacer Reverse eye A spring w/ a leaf or two pulled A wishbone w/ spacer A spindles Shortened pitman arm A brake actuator A kingpins 34 backing plates, brakes, drums Figured it will give about a 3” drop with the added benefit of 12” cast drums. The only thing I can see as a potential problem will be tire rod clearance. What’s a safe distance from the engine? Anything else I’m not thinking of?
I did this type of setup but used 1935 Ford axle, it has been a while now and the car has been on sold, but I recall that I needed to make a fish plate that bolted between the top of the spring perch to match up with the actuator. For some reason which I can not recall there was a difference in height. It was simple fix and brakes etc all worked well... Pitman arm is critical and it sounds like you have that sorted out.
Works great! A bolt together deal. You can use '32 brakes that are 1 3/4 X 12 or the '33/34 that are 2" wide. Make sure you get the longer brake actuator rods that go with the 12" brakes. You can also use the later spindles. You must use the wishbone for the chassis you are using: Model A- Model A, '32- '32, '33/34- '33/34 wishbone. I don't understand the spacer for the wishbone or the spacer for the A shackles- I don't think you need to do this. The axles are different thickness at the spring perch holes but a spacer or a little heat will take care of that. Great start for a very traditional pre WWII build. Good luck
Try searching the archives and asking on fordbarn. They guys over there do it on speedsters but I never paid attention to the details. Charlie Stephens
