I think my push pull and the fact that the leaf is mounted at the back is my trouble . Just wondering if I should update to newer leaf springs and change mounts around or should I try crossover steering ?
While crossover steering is the way to go, I think your steering/handling problems come from the steering box and possible caster angle.

RedHead steering gear is the only way to go for a first gen Dodge box (any steering gear really).

What is you caster set at? You are using the Dodge D60 front, right? If so, I am willing to bet your caster angle is in the 1 to 2 range. Get it up to at least 4 if not 6 to 8.

Another important thing is to use Dana/Spicer parts only in the kingpins - On my current 1st gen Dodge, I rebuilt the kingpins with NAPA cones and springs - truck drove terrible. Finally bought OEM parts and it was much better.

Turns out the NAPA cones were way softer so they were grabbing and galling and wouldn't let the wheels "self steer".

As for the leaf spring setup, my '66 F250 is pined in the back, shackle (actually slipper) int he front. I have been known to regularly cruise at 90 to 100 MPH. Drives great.

Re: My 56 6bt 4X4 build.

The OBS Fords (88-97) use the front shackle in the front and they drive ok. But it is a lot better when you put the shackle in the rear and even better when you put a longer leaf spring up front. Granted you won't get the coil spring ride quality of a 05 up, bu it is a big improvement.

If you go cross over, make sure to put a panhard or track bar on the front axle.

Ya I'd like to change front springs. I keep coming to the realization that if I buy new front springs, get some sort of perches and shackle mount money wise I'm close to buying a bunch of 4 link parts . Was thinking abt arms like this
