Hi all, I was wondering if I can get some advise on my center wall. I own a 1978 double wide and I'm planning on remodeling my kitchen and front living room. I want to take down the center married wall that divides my kitchen and living room, however I'm not sure if it would be safe to do so or at lease a part of it. Could I add a header at the center of the roof and brace it on each ends with 2x4 or 4x4??? [ATTACH]70860[/ATTACH]

Hello, I removed a soffit above a stand up shower in my bathroom. The replacement piece of drywall is 3'x4'. 2 sides of the drywall do not have joists above where the edges go. The builders put a 1x piece of wood on the top of one of the walls so you can screw the edges of the drywall into it, but the other side does not have that. On the side with the missing support the drywall edge will be unsupported about 2.75". There is a joist 2.75" away from that wall. The whole rest of the bathroom ceiling on that edge appears to be unsupported for 2.75" (I am only replacing one small section). I pushed on the edge of the existing ceiling drywall and it feels pretty firm even though not supported for 2.75" on the edge. Do I need to do anything about it? I cannot easily add blocking there because the builders put a 1x piece of wood on that same wall which goes to the OTHER room ceiling drywall. 2) Other question is the joists are 16 on center so two sides of the drywall will have screws every 16" at the edges. Is that good enough or do I need to add some 1x or something to have more frequent screws. Thanks!
