The gauge support is now glassed to the main dash, and recessed sections bonded in also. I've also added the tabs for the gauge binnacle surround to screw into.
It all needs a bit of a tidy up, but most of this front section is hidden by shiny OEM dash inserts so it doesn't really matter.
I don't like screwing just into fiberglass as after a few times of "put-on / take-off" it chews through the fibreglass and doesn't hold, I prefer to do it properly with metal fixings. I'm still waiting on some metal U-Clip connectors and nut fasteners to turn up as the first supplier cancelled after 2 weeks and refunded the money...grrrrr (why advertise if you don't have stock).
