Hi Don,

I get a similar noise speedo on my 71 bay window. The needle bounced
around like you are describing, also. Turned out to be that the speedo
cable needed lubing. I don't recall if I replaced it or squirted some lube
down it, but the solution was pretty easy.

Can't help you with the no-snap-in thing.
