Tearing apart my column

[asphaltburner]

Yo! 84 400 is correct,...you con't need a tool, but it does make the process, especially re-installation, easier. I've never used one on all the lockplates I've pulled. I just use a pair of pliers to push down on both sides of the lockplate and slip out the snapring. Installation is the reverse.
And, yes, the turn signal switch return spring is what's broken,...you'll need to replace the turn signal switch assembly with it's plug. Loosen the steering column bolts below the dash, and the channel that the wires run through below the steering column, and this process is easy. Just did my '78's recently. Todd.
