I swung into town and picked up a few more things.
New aluminum radiator as the old one was damaged, and only a single core anyway.
New Double Platinum plugs, oil pressure sensor, and water temp sensor.
Radiator installed!
I had to trim a small flange off of the passenger side header, as these covered the bolt hole for the oil dipstick
Best header gaskets ever...OEM!
Oil dipstick, transmission dipstick, spark plugs, and temp sensor all installed. I need to find an 80's adapter for the oil pressure sensor, as the Vortec one apparantly uses a larger thread than the 86 did.
