Ok, What have I done now... (904 problem?)

i figured it was 1/4 or so. and it sounds like fun LOL, been there, done that. its nice to have that drainplug. i have even drilled stock pans and welded in a plug. to this day i cant understand why Ma didnt make them with plugs. i would still put it back together the way you KNEW it worked, just to be sure, but thats just me.....
