I’m mounting the Roll Bar WD-641 on our RV-7 slider.I’ve measured as per plans from the pre punched rivet hole in the front fuselage skin then transfered line on the top of F-721B Aft Canopy Deck but on the transfered lines is different by 1/8” from the desired rivet to the opposing side.Then to drill the holes for AN4-6A and the AN3-6A the measurements are taken from a rivet on the F-721B they will be 1/8” different on the Roll Bar.I go over my measurements but reluctantly to proceed.Has anyone experience this?
