Auto part Washer Transmission part Grommet

My 1986 4bt was dripping from the oil drain plug. I found a skinny copper washer. NAPA sells a more substantial copper washer for under $2. It is thicker and wider. NAPA # NOE 7043007.

NOTE: 4bt parts can often be found by searching for 1990 Dodge D150 with the 5.9L diesel engine
