I put this all together before I decided I wanted to incorporate the Almost a 14 kit from anti-splat. I've got that kit sitting in the shelf already and it seemed like it would be easier to drill out these rivets now rather than later. I talked to several guys on VAF who said that it was no problem to have this x-bar just clecoed in for now, so I went ahead and drilled out 9 rivets per side and just clecoed it back in place.
