The stock 60-62 frame is the "X" frame that has torsion bar indepedent front suspension and rear coil springs. Since that frame was used only those years, suspension upgrades pretty much require some degree of chassis fabrication as there are no bolt on kits available. There are disc brake kits available and are typically expensive. Those years are also unique in that they also used a hydraulic clutch that had a different bellhousing/engine mounts. If the 62 you have already has the front discs and something different than the torsion bar IFS, then somebody has already done a lot of work changing that frame. As far as your 59 cab fitting, I don't know. It sounds like you have some homework and measuring to do.
