This isn't something thats laying around the shop but I figure it can't hurt to ask. My unit has a small crack in it but I can't seem to find out which tube it is so I need to order one. Thought I would check to see if someone has a repaired one or new. Once I get the new one install I'm going to open up the crack one to see if I can reapir it but I don't have time right now. Thanks
