On the bushing kit the two black one are for the shift coupler. Check the coupler beforehand to see if it’s needed or was replaced, expect some wiggle in the coupler bushings.
The cup and shift rod are the other two. The shift rod bush needs to be placed in hot water to make it flexible and will pop in easily. Look up JPNovak “Ultimate Shift Rod Bushing” here on Pelican Forum he has a hard plastic one that’s longer and I’m very pleased with its function and easy installation.
Cup bush can be stubborn to pull out and push in, silicone helps get it in easier.
Consider the throttle rod bushings too there’s 3 along tunnel, they’ll stabilize the rod from getting hung up. Also bell crank bushing on pedal cluster.
Essentially any and all old yellowed bushing should be replaced as tho will disintegrate unexpectedly.

As for wheel lug lock, I had a tire shop remove one once. Not sure if they had any special tool
but in the days of old, some grease monkeys would hammer/jam a U.S.A. Craftsman deep socket over the lock lug and it would grip enough to remove it. Then take the lifetime gauranteed Craftsman socket back to Sears Roebuck for a new one.
