Let me first say I can only speak to NAS (and not ROW 50th but its my understanding they are similar) because i did this to mine. if you search you could find my old threads. When the crossmember rots out, most of the time you need to replace the xmember extensions as well (or they are soon to follow with rot). And often the NAS fuel tank mounts can be rotted as well. The NAS fuel tank mounts are impossible to source but stephen peters has fabbed them up and they are incredible, well made, thick, better than OEM. Think about getting a xmember with extensions, stephen peters mounts, and a thick galvy fuel tank cradle. when the job is finished, prep, paint, waxoyl. Make sure to treat the crease on the leading side of the crossmember, fill it with grease, waxoyl whatever but keep the elements out of that area.
