Doc,
Which engine are you planning on using? I have the same plane and had considered using a DA 50 but after getting it (the plane) in my hands I thought the firewall looked alittle weak for that much HP, I do have a Moki 1.8 that seems to be a better match. The alignment of the horizontal stab on mine is a nightmare, it's either "plumb" to the fuse and alittle off on the side to side or on side to side and not square to the fuse, the "happy medium" took a good hour to find.
