Anything and everything Spitfire.

Hi all, still putting my car back together, i nnow need to refit the hood. the problem is that the hood frame is badly bent and worn. i want to replace it with a good second hand one, however am having trouble finding one. Would a markIV or 1500 frame fit? if so would it need th be modified in any way?The current frame has the same lock down handles as a mark IV. Anyadvice greatly recieved,as usual.
Regards Gary
