I want to order one of those lever operated valves to replace my oil pan drain plug (see link), but I CAN'T FIND MY DRAIN PLUG SIZE!! I've got an Alpha with the 5.3l. I've searched the Forum, and spent several hours on Google, and it's nowhere to be found. There was one post somewhere here that said possibly it was a 12mm x 1.75 thread, but I need to know for sure, so I can order the part for my next oil change. SOMEONE PLEASE HELP!
