I just received 2 Melling replacement rocker shafts from Rock Auto. I thought the plugs were not included so I ordered the plugs from Rock Auto as well, part #555-007, made by Dorman. Of course I had to order a package of 10 and when my order come the shafts did have them already installed. So now I have 10 I don’t need. If you’re having a hard time finding some let me know and I’ll mail you what you need.
