I put the progress dealing with the prop shaft and transmission and differential angles in another forum thread. While I was repainting the driveshaft, I also painted the front grill. The front grill, rear tail light trim panels and the hub caps all share the same paint. I bought the paint for these near the beginning of my restoration. If I recall correctly, I told the paint supply place the info for the color that is in the How to Restore your Z Car book. I painted the grill, but the color was too light - it was too grey, at least comparing to my original, not repainted hubcap. I got some crap in it too. So, repainting was necessary. This time, I took a guess, and added 10% of black paint (by weight) to make it darker. I think it came out a bit too dark, but I like it a lot more than what it was. I think I will experiment a bit more with it, adding maybe 5% of black and seeing how that looks. Then, I will repaint the tail light trim panels and possibly the hub caps as well.
