It's very common for the transmission to get shifted into 1st & 2nd at the same time. I had a 1974 pickup with that gearbox when I was a kid and it would shift into 2nd without dropping out of 1st all the time.
Chock the wheels, set the E-brake, climb under and shift the 2-3 & R-1 levers back into neutral on the transmission.
Three on the tree isn't that difficult to get back to working condition.
IIRC the bushings on the column tabs are the same as the automatic shift lever bushings. I'm really not sure about the transmission paddles to shift rods bushings.
