The holes may have paint in them but should be visible on outside rim of dish. Once I found them, it just took some time to get the arms attached & bent and the scalar centered. I bolted the lnb arms to the scalar first, then bent the four arms slightly toward the dish. Attached the top one (or closest to the top) first, then then bottom, then the sides gently bending each end into place and tightening hand tight. Once all four were attached I tightened them down and used a tape measure to check from several points around the dish edge to the edge of the scalar, gently exerting pressure on the scalar in the direction necessary until measurement is equal at all points checked. This gets the scalar facing the center of the dish and ready for your lnb.FTA4PA, Did you have any problems installing the lnbf arms? The reason is ask is because I can't find the holes to attach the arms to.
