What to do? I’ve collected 5 ’54 AD cabs over the last few years and a number of gauge clusters more. Just a little bit of disassembly showed me what I was up against.

Further investigation showed a fairly flat surface on the back of the stock speedo and that the gauges were not concentric with the housing but off set.

Tracing it out with a sharpie and cutting with a good metal blade in the jig saw left a decent clearance hole. A little filing and grinding opened it right up.

Just here for the free beer.
