Ronnie,When you find something that fits pay particular attention to the live/earth wires when wiring up.If I remember right some of the clocks have small insulation blocks fitted on the casings.I do know I've blown loads of fuses & been scratching my head in the past when things haven't worked correctly but sure you will get there.Regards Chris.
 
Ronny, There were two makes fitted on bombers Nippon Seiki & Fuji electric.If my pic comes through alright this may help you out.I found an old shell & rubber ring from a bomber don't know which make it is as top half isn't there but you can see the insulation bit of plastic and note it will still be insulated from the casing even when the bulb is lit.I.E two wires to bullb live and earth.(sure you will get my drift re this)Without actually taking a meter out of a bomber the best measurements I can give are 12cm one way and the 8.5cm the other i.e to outside of rubber ring.This rubber does push in so far into the shell but also compresses up a bit to hold tight ,it is a soft type rubber foam about 3/4cm thick.Think you could make yours fit(by making a custom rubber) into an original bomber headlight shell if you can find one but the correct dimensions on a bomber clock are 11cm X 7.7cm X 5cm deep.The actual rubber fitted is also same part number for CB160 but now obsolete 37242 222 000 .As Ray says the CB72 one will fit but sides of casing splay out to a wider diameter at the top and hence hold in with two screws through the shell and into the clock itself.Hope this helps regards Chris.

This pic gives you an idea how the rubber & clamp ring (proper term meter frame) hold the clock into the headlight shell.(ring fits in halfway up rubber and is clamped to bottom of speedo with 2 nuts.(In my view this clamp is a bit of a nonsense really but it does work. Have seen many clocks trying to make there way out of the top of the headlight shells:p Regards Chris.
 
Ronny,The hole in the underside of shells that fit CB160 & CB72 is a lot smaller than on an original bomber shell.Be prepared for a bit of cutting if you go this way.Its nice to keep both the speedo & taco cables in as straight a line as possible.Don't think CB160's had a taco cable at all. Regards Chris.
