I bought my 1985 K5 almost a month ago. It had been parked for a while when I bought it, so it has quite a few "issues". I don't know if a month counts as "lately", but so far I have:
Installed new windshield. Old one had a large crack in it. Got an exact replacement for it - the shaded top with the built-in antenna. Also got a new rear view mirror since the old one was loose and flopping around and a new pair of Bosch windshield wipers. Also got new chrome window gaskets for the windshield and two back side windows.
Installed a 14X3" K&N air filter and got one of those chrome Edelbrock filter housings. Installed new fuel filter. Changed the oil. Changed the transmission fluid and replaced filter and pan gasket. Installed MSD cap, rotor, and wires along with some new Autolite sparkplugs. Installed rebuilt Delco-Remy alternator and new belt. Was still losing power. Needed to ground the motor (duh) so I did that. Replaced all fuses and 552 blinker plug. Installed two Sylvania halogen top headlights. Flushed the radiator and added some coolant. Installed AC Delco battery and battery tie down.
Got a new set of Cooper Discoverer AT3 XLT size 32X11.50R15LT which I believe is the biggest size I could go on a stock lift without rubbing. Also had them mounted, balanced, and got a front end alignment.
Replaced the Suburban steering wheel that was on it when I got it with the correct Blazer steering wheel. Installed an OEM hood ornament. Repaired some chrome interior trim on the door pull. Wired up and installed the proper dome light (it was missing) and replaced bulbs in front and rear. Bought some cheap seat covers and floor mats to get me by until I find something else. Put all 5 exterior emblems back on that were missing - 2X "K5 Blazer", "2X Silverado", 1X "Chevrolet" on the tailgate. Ordered some NOS GM key blanks and had them cut at Lowe's for free. Bought and installed a set of the 2.5" chrome wheel bands for $30 from a local pawn shop. Went to the tag office and got a "Historical Tag" to match the year of my vehicle.
Factory radio was missing (of course) so I bought a cheap Pioneer Bluetooth + AM/FM head unit and installation kit at Walmart and then picked up two 3.5" speakers for the front, two 4"X10" speakers for the back, and an Alpine amp at the same local pawn shop. Haven't installed all this yet but I'm shooting for this weekend.
Swapped out my winch bumper (with boot $$$) to a local guy for his 1989 Suburban bumper with the big chrome bumper guards and wide rubber impact strips with the chrome strip on top. Did the half-inch PXE pipe fix for the door strikers.
Broke a piece out of the grille while working on the bumper so I ordered a new grille and the two headlight bezels from LMC. Parts should be here tomorrow.
I'm sure I'm forgetting some stuff. I currently have a 4 page "To Do List" and it keeps getting longer instead of shorter.
