Oh also, sorta-update.
Bilstein HD front and KYB Gas-a-Just rear shocks arrived from RockAuto today. VP shipped my seat clips, new brake booster valve and gasket, and some small hardware stuff today (Eta of Thursday), Pirelli webbing and pinch clips will get here Saturday, and I scored a set of $45 NIB Hella 500's on eBay that'll get here next week.
I figured out at least part of my high idle issue. I was getting gas today, and fiddled with the carbs and decided to pinch the booster vac line and promptly discovered that the idle dropped about 500RPM. The booster works well when the engine is under vacuum, so I suspect the valve/gasket is leaking enough air to create a problem.
