Installed the shaker tonight. It took a little more clearancing by Eric on the Lokar throttle cable adjuster, but she's in there now!
I reinstalled the dash and stereo tonight. I also cut the original glove box to clear the VA evaporator and ECU, and we're going to bond a new ABS back to it so that I have have a glove box. I'm losing about 1" of depth.
A few baby steps closer!
