thanks for the info JOn,,,so they must be all welded shut,,,anyway to get a picture of how they are welded,,,???,,does it look a bit crabby like welded all over,,,or just some small welds so the unit still looks un-altered,,i've seen some with nice small welds,,,and others which look like they took a stick welder to it,,LOL...i'd love a unit that looks original,,,,thanks for your time,,
