WANT TO BUY: Way to connect fibre-optic cable(s) to a WPDC21 housing.

I've just bought a little used Canon G9 and new, unused DC21 housing on e-bay as a back-up for my Olympus E-PL5 and Nauticam housing. I want to be able to use one (or possibly both) of my Sea & Sea YS-D1 strobes with the G9 set-up. I already have two L-type fibre-optic cables so just need the black plastic or velcro mount with the cable connector, not the whole kit. If anyone has one for sale, I would be glad to buy it. Or perhaps someone can suggest an alternative solution?

i used these in the past, but they have none for the g9, maybe a diy solution can work:

Many thanks! Reef Photo's double mount should be perfect.
