I am chasing the following for my 85 K30 Chev pickup build: Air flow direction box (mounts inside cab on heater box directs air to upper air con ducting or down at floor); Right and Left hand side air conditioning ducts; Engine wiring harness (6.2 litre diesel)(preferably unmodified); Diagram showing factory placement of dual fuel tank switch, Front wiring harness for 85 Silverado (with air, dual headlights, diesel)(unmodified prefered). What else have you ? Quick payment. Vendor must be prepared to clean, pack and ship to Oregon or Australia, at my expense.
