more on the full width swap
The full width swap has been popular here in the southeast since the mid 90's. First with the '78/9 full width D44s and 9's then with the '78/9 D60's and rear 60/14bolt for some. Most from back in the day just simply maintained the Cmounts/wedges on the full width D44 and used radius arms to the outside of the framerails instead of under in factory location. This accounted for the "wider cmounts/wedges" of the full width D44s. A couple of things that will help you, cut off the factory cmounts on the full width and get the "aftermarket" ones fromt duffs-that will allow you better control of your caster and radius arm placement. My rig has the duffs extended arms on with dual shocks and coils. Pretty much old school stuff but it works well. As was mentioned-links work well and you are not confined as much with the cmount/wedge issues. Lastly space out your coil mounts at least 1.5" off the frame when you do the full width axle swap to avoid the interesting "bow look" of coil springs on full width. HTH,
