Got the engine running fairly well and went to take it for a cruise it's first since 1968 and couldn't get it in gear, clutch was fine and everything worked as should except trans. Pulled the top cover on the trans. Mud with water in the bottom of trans, so i put gear oil on everything and let sit for awhile started engine and worked the trans till it finally started to work. I guess my question on these closed tube drive shafts is does all the trans oil also lube the rear ? Don't really want to pull the whole thing apart. Any suggestions, oh bye the way it is a 38 chevy truck 1/2 ton .
