Axle Placement for LB to SB

[ryanroo]

i think generally the frame is shortened in front of the leaf spring mount the appropriate distance to account for the distance change in a LB vs SB. if you are just moving the axle and lopping off the rear rails i would think that number is the same. i believe the difference in wheelbase that is accounted for by the bed in front of the wheels in a LWB vs SWB square is 14"
