last year I found the right gas cap for another 61 I had. I just bought another 61 and need another gas cap. Did I post the part number here? did anyone save it? I couldn't find it in the napa book this time.
the 61s have to be non vented caps. they have a separate vent tube that comes out of filler neck then vents on passenger side. If I put a vented cap like later trucks have it will pour fuel out everytime I take a right turn.
