Progress continues to inch along until the world cools off.
One thing that has been bothering me is the fit of the left door. When I was assembling the body I just couldn't get it right, and finally settled for "good enough". But today when I closed it it looked like the door moved up just as it latched. I loosened and lowered the striker and now it fits perfectly! Turns out I had the hinges adjusted correctly all along.
I also replaced the "Super Sport" dash plate with a "Malibu" one, and in the process discovered that my new lock for the glove box is broken. Explains why that never worked quite right. Hopefully a replacement lock will fix it.
The only thing that might be worth a picture though is the brace I added to the battery tray. With that on there the stock clamp holds the battery really well, and I don't think I'll bother fabricating any other system for it. I also added the battery cables, the local O'Reilly had them in exactly the right lengths.
