I got the Speedhunt tach installed and it works.
This is what the reproduction in dash tach looked like after breaking it open. It was held together by some blobs of silicon.
Looks like the Speedhunt unit can be installed in the old tach housing.
Test fit
I did have to cut the housing a bit. The side that got cut was slanting in.
I will say I give the aftermarket tach housing an "F" for quality. The fit of the lens and bezel was very poor. There was 3/16" gap on one side of the bezel. However at least when it's put together and installed you cannot see the poor fit of the parts. One of the reasons the tach was held together with silicon was because the parts just did not fit together. They used silicon to bridge the gap.
I did remove the lens on the speedhunt unit. There might be glare if I had both the Speedhunt lens and the GTO tach housing lens.
They glove box took far more time than it should have, but it turned out well.
I added a light strip to light up the box. The factory light is almost useless, I also installed the USB port for the radio in the glove box. The trunk release has also been mounted. This is a shot of the glove box in the dark.
Another view - You can see the light strip here. The green unit is my USB strip. I used a panel plug to hide the hole left for the factory glove box light.
Still fighting the windshield wiper motor. I got the replacement for the damaged one and found things still didn't work right. I have only one speed and the park does not work. After testing and tracing wiring for a while, I believe the wiper switch I have is for a non-park wiper motor. It was on of the few things I did not replace. I didn't replace the switch because I don't expect to need wipers very often. That is so say I don't plan on driving the car when its likely to rain. It turns out that the original wiper motor was completely shot, extreme wear, no grease, the switch that reverses the motor was cracked. Anyway I ordered a wiper motor switch today.
