- Notes
- Radiator filler cap for John Deere A, AR, B, D, G and R tractors and the 60 standard, by serial range per one reseller. Deere still sells it: a dealer quoted $46.36 as a special order, not in stock, and Deere lists a height of 4.5 inches. A reproduction at $20.00 was sold out. Contact with hot coolant puts it outside PorkForge's printable range.
