Got it running today, runs good but very little oil pressure, changed to a good working sending unit still low. A lot of miles over 200 I’m guessing. Might be strainer stopped up, my 90 RC did the same and found that under the intake was crusted up oil deposits that had broken up and clogged the strainer so might be next option. Brake pedal would go to floor like out of fluid added some nothing. So after backing the truck out after getting it running there was a rusty adjuster laying in the floor, so out to look and no brake drum!!! The things I’m having to fix on this truck is incredible, Idiots must have worked on it thru the years. I guess free was to much for this truck.! Onward
