I am currently working on the fuselage bulkhead that the rear spar bolts to behind the seats. the issue I am concerned with is that the straight spar attach piece is 1/8 of an inch longer on each side than the bent piece (f605k I think). My question is, how far does the rear spar slide into this space and will I have enough edge margin to drill the mounting bolt hole, or is 1/8 of an inch not an issue. Thanks Bob Collins
