I was able to get one of them to fit.

My rev counter has been acting wacky ever since I installed an SD1 dissy.
It'll need some soldering skills and the ability to input a signal from a sound source in order to calibrate, but that's not impossible.

It took me approximately an hour to convert mine. Simple as pie. The most difficult part was hiding the additional wire. Find the link RIGHT HERE.

In order to convert my P6 Series 1 Smiths tacho from RVI to RVC, I have tried everything from soaking it in penetrating oil to heating it on a stove to stretching the bezel rim with a screwdriver to turning it back and forth by hand to clamping it with grinding paper in a vise to using a large cloth-covered pipe wrench (don't worry; it survived). Is that what you meant? Why wouldn't the bezel turn if there was a problem? what is the answer, if any?

I though I'd throw in my two cents here in case it helps anyone: mine wouldn't turn on or would get stuck at 500 RPM until I figured out that the dial was touching the spindle and preventing it from turning. It stopped operating, but then it began working again when I pressed the dial against the casing in the other way. I found an adjustment on the rear (often hidden by a seal) and fiddled with it until the idle was exactly perfect.
