Sorry man, I'm sure you can understand that I've been a little distracted!
I got the muffler on the car last Friday, and spent a couple more hours driving around on the way home. For the benefit of everyone else, there were a few outstanding items when I picked the car up (none of them were Chris's problems - they were almost all parts that I hadn't ordered or that we were waiting for). The missing muffler was the most notable item, so it was good to get that completed. I had to remove all the spacers from under the driver's seat. That tells you how much the original seat cushions had collapsed, because I never had any trouble fitting in the car back in the day. Even with all the spacers removed I'm brushing against the headliner with the seat back and reclined. The rear sway bar links that I'd ordered months ago were the wrong ones, so the sway bar was in place, but not connected to the suspension, which was the suspected cause of a clunk happening when hitting bumps. I got the correct links (unfortunately I mistakenly ordered only one first and had to order a second) and installed the second one this morning. Unfortunately, the clunk is still happening, and I'm starting to think it might be coming from inside the passenger door. The other suspect is the gland nut on the passenger side strut. I might not have tightened it down properly when I re-assembled them a couple of years ago. The tach isn't working consistently, so I need to order and install a TechMatch device to sort it out (I believe it's the TachMatch TM-03 I-Drive that I need? Current-driven tach?). I'm not confident that my ear is good enough to recognize redline, so I probably haven't gone past 5000 RPM yet. The engine sounds and feels absolutely great up there, though, so I'm looking forward to really trying it out. The throttle's a little sticky, which made driving without a muffler quite interesting. It's either getting better or I'm getting used to it. The linkage all looks fine and all the pivot points are properly lubricated, so I'm going to keep driving to see what happens. The gas gauge isn't working, which is mysterious, because Chris and I both had the sending unit working properly, and I think I tested it once when connected to the gauge in the dash. It's probably something simple, but I haven't got to that yet.
Mostly I've been driving the car, which has been fantastic! It's starting to come back to me. As I mentioned somewhere a while back, the engine somehow feels much larger than it really is when you first start driving it. That long hood has something to do with it. The car's already starting to feel smaller and more nimble to me after only a few hours of driving. I'll keep driving and knocking these items off, and I'll keep this thread updated!
