the leafs are not only holding the truck up, but they also locate the axle in all directions.

to remove the leafs, you'll need to fab a 4 link setup and coil spring mount perches, the easiest way would be to fab up good mounts and run coil over shocks vertically.

the geometry of those upper bars is pretty badly designed IMO, would create really excessive amounts of bind when the axle moves up/down on one side. Could alleviate some of the problems with spherical bushings instead of the poly bushings in the upper bar ends.

the binding would cause snap oversteer when going around corners aggressively.

i really like the coil setups on the late 60s? chevy trucks. late 60s early 70s i think.

Not the best design IMHO, but they worked. my dads old '72 GMC was coil sprung and had a BBC (402) in a 1/2ton 2WD. You can see the arms hanging down in the picture.

i was looking into the 4-link setup, that i posted above cause it was a Canadian company, and is a similar setup to the 4-link in my Lemans
