The Spyder's gas gauge read halfway between 1/4 and empty so I drove to the gas station & added 8.8 gallons of 93 octane, which filled the tank, so I'm calling that gauge perfect. The car feels stable and stops straight. Shifting is still easy (though 4th was a bit hard to find the first time).
Both doors rattle just a bit so I guess it's time to install the weatherstripping I bought.
There's 5 1/2 inches clearance under the floor just behind the front wheels, and 5 3/8 just ahead of the rears. Stance seems good.
This headlight is aimed a little too far right and probably too high. I may have to pull it to get the adjustment right...
Steering wheel needs to come off and get re-indexed to make it straight and get the turn signal cancelers to work. I made a thing to poke the horn button out from the inside but it didn't work the first try and I'm pretty gun-shy about damaging that part. Any advice appreciated.
Still trying to decide what to do about the firewall upholstery. The more I live with it the more I feel like we're gonna be able to live with it. . . .
Cleaned and reinstalled the floating floor.
I do think the interior turned out pretty realistic...
Once again, thanks to all who have supported me in this foolishness.
