I know I've seen someone post about where to source the little rubber grommets that hold the bulbs into the instruments although it may have been in years past.  I've searched but cannot find it.

Does anyone know a source for these?  Thanks

Yambits in the UK do complete bulb holder, rubber grommet and wires, although they are all blue and black wires - ie colour coded for the backing lights.

Vintage connections in the US might do something.

You could look on fleabay for a cheap wiring harness/pigtail that might have decent bulb holders attached to them.

When searching the forum, be sure to use the "Search/Search Forum" button on the lower toolbar.

I'm assuming it's a 10mm hole? Exy, but it you gotta have :(

Thanks for the search tip.

I'll keep looking or just make up something. Thanks all.

I bought mine from Yuniparts years ago when they were still around. 

Gr8uncleal said Yambits now has them and they do...  yambits.co.uk/ct3-tacho-speedo-bulb-hold...sembly-p-100364.html
