After drilling these 1/4 inch diameter holes (for the AN4 Bolt), these hole s are too close to the weld fillet that welds the torque tube to the perpen dicular part of the Horn. -The w eld fillets on my L & R Horns go ALL the way around the Tube. Thus the AN4 Bolt HEAD and corresponding Nut HEAD will come in contact with the "weld fillet" BEFORE they are tightened. -- - After reading the "Archieves" for possible solutions and some of my own thoughts it seems the options are (looking for the BEST Option): 1) Die Grind the weld fillet in the area where the Bolt and Nut heads will be, then spot prime with Zinc Chromate. 2) -Grind the weld fillet where the Nut Head will be and then use a reduc ed size Nut (MS21042-4) that has a smaller diameter than the -one supplie d by Vans. 3) -Use regular AN960 Washers and "contour them" to fit over the weld fil let so Bolt Head and Nut fit snug against them. -(Will need a longer Bolt than supplied by Vans.) 4) -Make a "thick" washer out of stainless steel (i.e. 1/8" thick) and "c ontour it" to fit over the weld fillets; thus the Bolt and Nut heads have a flat surface to tighten against. -Again a longer Bolt will be required. -<----- Seems the BEST approach to me. - Any subtle issues involved ???

I believe that grinding away the fillet on a structural weld is a bad idea, leaves a stress riser and weakens the part.

Just checked my parts, my hole is close, but it has enough space for a washer and bolt head between this hole and the weld.

My bolt head and nut were clear of the weld, but just barely. I think I'd go with option 3 or 4. I'd try one and if it didn't work out I'd try the other. I don't think I'd grind away any of the weld.
