Cur 3/4 x.062 angle and fit to F-12. Cut and shaped 3/16"x 1.5" angle for tail bracket. Fit bracket to F-12 and drilled bolt holes. Couldn't fit AN3-4A bolts through all holes because hole spacing was too close. Tried to modify the mounting to use 2 8-32 SS flat head machine screws to make it fit. Totally unsatsifed with final product and elected to scrap all work on F-12 and redo properly
