1989 Chevrolet K1500 4x4, needs engine ,silverado,c10

This is a 1989 Chevrolet K1500 4x4 short bed pickup. Body is above average for the year, only 2 rust areas on entire truck: passenger rocker and the cab corner. I have both patch panels to go with the truck.other than that truck is solid, floors look great. inside bed has some small dents but solid.
Both doors could use bushings. Engine has a major knock, will need replacement. I purchased the truck as it is so i do not know how driving components function. exhaust is fairly new.
Thanks for looking, D.L.
