early instruments, black cups

I have a set of earlier instruments I want to use on my 850 with the black cups. The threads are too short. Anyone found a work around?

Smiths instruments need (x4) pillar screws (item 2).

wrap a couple/few turns electrical tape then push into cups... let the criticism begin

I say if you can make it work and you like the result , go for it , you out to please yourself , right ....

I have fitted Legendary GPS speedo and electronic rev counter. The suggested fixing method is to smear silicone down the side of the instruments before sliding them into the pods
For me this caused a few concerns
1. The sliding fit of the instrument into the pod is "snug" but not enough to stop it turning and lifting, but in some positions they jammed & with the RGM lower pod plate assembly fitted there is no real way to get a finger or probe in to push them back out and risk damage to plastic casing or internals
2. Applying even a small amount of silicone IMHO will make the situation significantly worse, as once the RTV has set there will be no way to get them back out.
3. Any misalignment when installing will be permanent
So I decided to descreatly drill and tap the pods and insert short 4mm stainless taper point grub screws.
These just bite into the plastic casing of the instrument without damage, allow them to be easily removed and re-aligned if the pods have been taken off
As mention earlier let the tirade commence

Sensible solution, Malcolm....

Speedo should be on the left, tach on the right.

And the beauty of not siliconing them in, it's a really simple task to swap them over

Thanks LAB for the link. I ordered a set of the pillar bolts. Those are also used to hold the points plate and cover.
