April 10, 2011:
The shifter surround that I snagged a few days back fit exactly over the tabs that hold the panel around the shifter in place, making it quite useless. Fortunately, they are in demand, so I was able to recoup much of the price I paid. There ends this entry's fail.
Between yesterday and today:
* I swapped the centers of the steering wheels between the Pearly and the Silver. The one in the Silver said "Impreza" on it, and it's surely not one of those. It now just says "MOMO". Trick of it is, I wanted the cruise control switch to stay with the Pearly, partly for keeping it active for some possible future buyer, but also because it may as well stay, as the wheel in the Silver doesn't have a hole to accommodate it. This meant a lot of messing around with the bracketry that the airbags mount to the wheels with. I also had to do some goofing around with the horn wiring. I didn't even get around to taking pictures during it all. Maybe I'll shoot some later.
* The antenna is finally installed. This turned out to be a real pain in the ass. I don't know if there are different antenna bodies and different trim pieces, because these surely didn't match. There was a key on the antenna shaft that didn't have a matching keyway on the trim. The trim had a pair of legs that collided with a land on the antenna, keeping the mating surfaces too far apart. All told, with a file and some needle nose pliers, I was able to rectify the obstructive bits and all went together. Some time ago, I'd installed the new side lamp bulb holders, so my business behind the trunk panels is complete! The trunk is all buttoned up and good to go.

* Lewis had snagged me a piece of trim to complete another project. There's a C-shaped plastic piece that goes on the back deck under the glass that covers the wiper arm shaft, which is installed as of today!
I've got some great ideas on how to get the DCCD working. It could actually go right through the Hydra for automatic mode. Details as they roll in!
