DVIDOG8793 you are my new best friend.
Just bought my new 84 G20 diesel Van conversion with 000273 miles on the odometer. Interior and exterior looks like it is maybe 5 or 10 years old, not 30.
Bought new Michelin's on the way home 235 70R15, one problem solved.
List of questions:
What kind of oil and how much to do an oil change?
What oil, fuel and air filters do I need?
Where can I get a chart of all lube points?
The AC/heater controls do nothing, not even fan. where do I start?
The seller installed a new radio. It lights up but no sound. Where to look first?
The gauge lights are so dim I have to look close to tell if they are on, is this normal? Is there a fix?
