Cut the spring perches off your 1 ton 14b. Make the tube all smooth and pretty. Wheel 1 ton 14b under the truck, attach new perches to the bottom of the spring pack making sure that the center pin is in the locating hole in the perch, and lift axle up into perches. Measure from the outside of the perch to the flange that the drum backing plate bolts too and make this distance the same on both sides. Also make sure perches are 42.5" apart on center. 1 ton perches are 40.5". (measure twice, cut, or in this case, weld once.) Use another jack under the pinion to rotate it to the correct angle, then tack the perches to the tube. The rest is easy....Lower it down and weld it up. I'm sure there are different methods/variations to doing this, but this is how I have done it. /forums/images/graemlins/pimp1.gif
