questions about the roof of a 29 model A

I have a 29 model A been chopped and a new roof put on ... the roof from the middle of the car forward is great but from that point back it is "ugly" wavy... I have a metal strut across on the inside in the middle the rest are bowed wood. now I noticed yeasterday when taking a closer look that the 3 struts towards the back are almost flat not bowed like the rest of them I can acutally push up on them and it makes a very big difference in the way the roof looks not as "ugly" of course when released they fall back down... now the ones in the front that are wood are very rigid is it possible that someone replaced these with some softer wood? I was wondering if there are metal ones I can but and screw on top of the wood pulling/pushing the roof into place? or is there somewhere I can by the correct ones?? Or does anyone have any other ideas?

thanks,

Don't know about buying metal supports, I've always just made my own. Hard telling what they guy who did the chopping put in for supports. Could just make some new ones out of wood if that's what you want and put the correct shape to them..... Curious, is the car a coupe or a sedan....?????

It is a tudor sedan . what type of wood should I use ? a hard wood like oak?? the only other problem is that he has glued them to the roof with some very very strong black glue I don't know how to remove them

Oak should do...might want to ask some of the more resto type guys, I usually do all my roof supports with metal.... but yeah, IMO a hardwood would be best,,,,,, as for the glue, might be a real booger to get the wood strip off. Might want to try a heat gun and a semi-rigid putty knife with a sharp blade......
