Pics as promised:
It is actually way simpler than I thought to get the miata seats in. I just got one in because I still needed time to work on my motorcycle (four carbs suck).
I'll probably put the drivers seat in next weekend. They will have to come out again when I put in carpet. Plan is to have most of, if not all of the interior done by the end of summer. I want to put in a modest sound system, sound deadening, carpet, dash cap and a full gauge swap. Haven't decided which gauges I'm going to do, but I'm leaning towards Autometer Phantoms.
