I took the tailpost and F23-04 angle off the tailcone box and drilled/clecoed the tailwheel mount to these, so far so good. I then put these back on the tailcone box assembly so I could fit and drill the F23-03 forward lower mount angle to the longerons and here's where I made a mistake. the F23-03 angle must not have been clamped correctly or tight enough, after drilling it to the longerons I took it back off and noticed the holes where shifted to one side of the angle and therefore one was too close to the edge. I'll have to remake that angle.
