I've given the head lights a rest for a bit as I was getting frustrated with them. I'll attack them another night.
Since then, I've managed to install the E-brake units
Install the AC unit.
Drill and weld up the steering wheel adapter, mock up the seats for placement and get the e-brake handle situated for final placement when the shifter gets mounted.
I've managed to get one side of lights to fight right with a lot of fiddling with a drill nibbler/grinder attachment. Now, getting those plastic nubs to fit properly... that's another story.
I also figured out the right combination to get rid of the packing tape residue.
Liberal amounts of goof-off, let sit for an hour or more, scrape off with plastic razor repeat if necessary.
Finally, while it looks like i'm just playing making race car noises, i'm actually fitting myself for seat angle, height and distance from roll bar to my head with my helmet.... But mostly race car noises.
