This thing is determined to make me crazy.
On Friday, I swapped the Bilsteins in on the rear. On Saturday, I ran the amplifier wiring into the cab and wired in a quick connect on the back of the radio so I could swap the speakers between the radio and the amp. Got the wiring laid out enough that I could fire the system up. Sounds great other than some alternator whine that I'll have to deal with later.
Once the amp was ready, I took off on a 200 mile round trip to Charlottesville. Things went fairly well on the way out aside from desperately needing to get the wheels on a good balancer. My bubble balance got them close enough to run on the interstate, but they're definitely vibrating.
On the way back, my oil pressure gauge lost its mind. The needle just started flying all over the place on the gauge with no correlation to RPM or anything else that I could make sense of. No associated engine noise at all. This happened once about halfway back just as I was pulling in for gas. When I restarted, the problem went away and never recurred until I was pulling back into Roanoke. Happened again as I was coming through town. I'm going to try carefully reseating the connector to the sender. I'm pretty convinced that the issue is electrical, but would hate to be wrong.
