Default 1990 K3500 time for new transmission

Just wondering if anyone could help I have a 1990 Chevy one ton with the 7.4 and 4 speed in but the 4 speed is out of it and just wondering if there was a 5 speed transmission that would bolt up or should I just rebuilt the 4 speed?

Is this a manual transmission?

Nv4500 is a worthwhile upgrade, but it's slightly longer than the sm465. The trans itself is more expensive plus the cost of driveline mods.
