Help with Temp, Gas, Oil Alt gauges FREE VIDEO INCLUDED!

You have a factory service manual? Go over to MyMopar and download one/ some for free..........SOME of those there came from the guys right here

EDIT........below is 67 later...........
Drop the column down, remove the battery ground, and remove the cluster screws. Reach up in and undo the speedo cable. 67 has a screw on, I think later ones are all "clip" on.

Sort of "tip" the cluster down at the top ....the rear of the speedo sort of "hooks" over the lower part of the dash frame
