I'm back at it this morning. After my wife left for work I went to the garage to play. I have the first plug drilled and fitted. I have not trimmed the bottom down yet. I'll do that after I get the other one fitted and drilled. I don't have a Bridgeport at my disposal so I have to do this all with a bandsaw, drill press and dye-grinder so this will take longer than the preferred method. I'm not complaining, in fact I'm quite thankful I have these tools in my garage. Time to make the next one. After I get them made I will install them with aircraft fuel tank sealant to seal the top of the airbox. http://www.aircraftspruce.com/catalog/cspages/ac236b.php?clickkey=4275
