Speaking of the dash, IMO one of the more interesting and maybe challenging build sequences to mull over is upholstery and dash assembly.
Background: I am upholstering the dash in a leather similar in grain and feel to the roadster seats. I am also adding a bit of foam (either 1/16" or 1/8", depending on where it is being applied) for a bit of "feel".
The stock dash is not trivial, in that there is a separate gauge panel, end caps and gauge visor. Add to this the option that one may wish to have fasteners either revealed or hidden (or some combination) under the upholstery, and sequence gets a little complicated.
Let's look at the visor for example. One is not going to stretch a piece of leather over the dash and also accommodate the visor in that same piece. The visor likely needs to be upholstered separately and then attached almost last in the dash build sequence. This implies that the fasteners to attach the visor are probably not cheesy rivets, rather maybe some nice button head machine screws. This implies appropriate use of rivnuts. Perhaps the same attachment scheme that one might use for the gauge panel. (Note: I decided early on to make the gauge panel easy to remove to gain access to the wiring nest behind the dash - this implies the gauge panel is "outside" the main dash, and attached with 8-32 machine screws.) The visor sheet metal is maybe 0.040" (or whatever), and if I am going to use foam as a leather backer, this suggests where I might use 1/16" versus 1/18" foam at certain places for a nice transition between top or face of dash and top or face of visor, for example.
The end caps are maybe easiest to think about. They can be done first, both foam and leather, without any dependencies, except as may be related to accounting for the leather thickness for proper bending of the tab that attaches to the cross rail. These layers can be bonded with a spray contact adhesive.
Independently, the dash proper can be done. Spray contact adhesive can be used for the foam layer, noting the cutout areas for where the visor might attach (no foam here). And then the dash is attached to the frame and firewall using rivets and/or machine screws where appropriate. And then I need to lay down the leather. This sequence is my doing, as I want a smooth top of dash, without fasteners. Using spray contact adhesive at this point will be a mess, so a brush is used. Wrapping and clamping the leather is a bit of a pain in the A$$ with the dash already installed (and wired, and ...)
Well, it IS Friday, and I am about to call it wrap (no pun intended) for the weekend (as the snow and skiing is first class ATM)
I am using all available flat surfaces for assembly these days. Here is one of the aforementioned dash end caps in the middle of being upholstered. Note it is resting on a charcoal gas tank vent filter of Edward B's design. As well as the gauge panel being wired for ground and power (bullet connectors in the works for easy removal of the panel as suggested).
