From searching and reading Smitty's log, I see that I am not the first person to realize that the e-902 and e-906 elevator spar and rib are pre-drilled for the wd-605 horn. However, when I test fit everything together (ie I have not yet riveted e-902 to e-906), the holes in wd-605 and e-906 are about 1 hole width off. I have cleco'd the horn to the spar, and then hold the rib in place to check alignment. I am hesitant to rivet the rib and spar together yet before I am sure that they will fit the horn. Perhaps riveting e-906 will compress the flange enough that it will bring the holes together but I doubt it. Has anybody else run into this? It would almost be easier if e-906 was NOT pre-drilled here.
Planning on emailing Vans but thought I may get some advice here before the weekend is over.
