I have 2 boxes of 10, NOS, Champion H-11 Spark Plugs still in the original boxes. These are the cadmium plugs post 1956. They can be easily stained black for AACA judging by a light brushing and staining with gun blue. I want $20 per box (10 in each box) plus shipping. Also for sale is a brand new Trico lid for the windshield washer bottle. the lid is coated silver. I want $30 for it plus shipping. Most of these lids are rusty and the paper seal is deteriorated. If interested Email me at email@example.com.
