Are the broken "spuds" the arms that are directly behind the upper shock mounts? If so, then you should be able to take the chrome "U" bar that slides over the ends and connects them, to the welder. If the "U" bar is in place, the distance will be correct, he will just need to make sure the level is correct. If the bike is all together, insuring the licence bracket, chrome covers etc. align after tack welds is made, all should be good. Alignment perfection in this area is more cosmetic
than safety.
