Just replaced the BLS on my '69, too
The chinese crap replacement switches are of inconsistent quality and sometimes don't last long. Check the brake lights when you exit the truck even after the replacement.

That's what caught my eye, I noticed the reflection on the wall in the garage and thought "that's weird". When I went to adjust the switch I noticed the pedal actually wobbled just enough to relieve the tension on the switch. I am hoping that after I replace the nylon bushing things tighten back up. If that doesn't work I was thinking of getting an adjustable master cylinder push rod.

The lower switch is 1968/77 (manual or power brakes makes no difference) and threads into a retainer (13A629 in pic) that clips onto the brake pedal.
The retainer clips to the pedal with prongs. Some/all of the prongs break off, the retainer then either hangs from the pedal or falls off of it.
Pic: See 13A829 retainer and 13480 switch at lower left. 2A309 is the nylon bushing for the push rod.

The upper switch is 1967 only.
The lower switch is 1968/77 (manual or power brakes makes no difference) and threads into a retainer (13A629 in pic) that clips onto the brake pedal.
The retainer clips to the pedal with prongs. Some/all of the prongs break off, the retainer then either hangs from the pedal or falls off of it.

Check to make sure that the prongs of the retainer are still clipped to the pedal (it appears that it isn't).
If it's not, the switch cannot be adjusted.

Would there be any difference with this plastic switch? I already found that these cheap metal nuts don't tighten worth crap

don't tighten worth crap.The switch threads into the retainer. If the retainer breaks (common) and people don't know where to get a replacement, they use nuts instead.
In Steve's pic (post #2), you can see the nuts, but they were not there originally (see parts catalog pic in post #8).

I had the same problem with the lights staying on. New switch doid not help.I cobbed in a spring that hooks to the dash. I think the root problem is wear on the pedal boss. Maybe some lube would help.
I am thinking about a pressure switch at the master cylinder. Anybody have any advice on theat?
