FWIW - here is my previous to-do list... (EDIT: I see that the strike command isn't enabled/working for this message. Items 2 & 3 on this list are no longer of concern to me.)

1. Odometer sticks - $0 to fix
2. Engine has blowby - teakettle test had oil spray all over and rad cap really jumping. PO says a valve adjustment will help - I am not sure when the last one was done. Is it worth it to buy the kit, or just the wrenches? Engine may be worn. Not sure. Swap??? - $180 for valve adjustment kit with wrenches, gasket, feeler gauges, etc. upon further reading, I don't think this is an issue. The cap stays on the engine and some oil spray is normal.
3. Oil pressure gauge is pegged to the top while driving - I don't know what the normal position for the gauge is. Rings shot? Sensor bad? Gauge bad? (Could be pricey - dunno) Apparently this is normal
4. The dash is all original - including radio. But no lights work except the dim speedo bulb. I think I can get bulbs for the heater gauges, but how do you light up the radio? - $20 in bulbs
5. Power windows don't work for the back seat. Any common problem I should know about there? - No idea, likely an electric fault
6. Driver's door lock has vacuum issue (you can hear the vacuum fail when you unlock the door). Not an issue - can fix over a weekend. - $30 part, $30 vacuum tester
7. Power antenna only goes 1/2 way down. any ideas for a fix there? it looks straight, but is pretty gummed up. Last car I was able to just clean the antenna and then it worked. - worst case is replace power antenna - $40
8. The engine is pretty shaky, so it wouldn't surprise me if it needs new motor mounts. - $100 in parts
