Making great progress on these. I think it helps a lot to do a little at a time on big jobs like this. Keeps my mind at ease and I can actually see progress. Fit is good Laid some grease on the back side of the mounts to see if it would transfer to the main spar. Good contact between the two. Yes! Reamed out the holes and got rid of the powdercoating in the holes so the bolts wold fit. Mounted brackets as per hardware callouts. Used AN4-13A bolts to mount, torqued to 60IP
