To my knowledge, no. There were manual locking hubs with the NP205 T-case, and locked hubs with with the NP203 (full time). With the latter, the hubs were always engaged, and your drive mode was selected with the T-case (4lo, 4hi, locked, etc.) I know many guys swap out the locked hubs for manual ones so the front drivetrain isn't always spinning.

chances are those had the "plugs" that basicaly locks the front end solid, and the hubs always engaged. The 203 trans case works like a differential, if it isn't in 'hi-loc' or 'lo-loc' it will slip and power will go to where ever has the least traction, front axle or rear axle, but both axles are always engaged(hence the nickname "fulltime 4x4"). However, some 203 trucks have an aftermarket "parttime kit" with lock outs on a 203.
