Hi Jeff. Those R13’s are big buck lights, aren’t they?! I have been on the hunt for the GMC 41-46 brackets too. I ended up buying the 1934-1936 brackets from Jim Carter and will use those until someday on the off-chance the 41-46 brackets ever show. Not sure what’s up with The JC website these days - it’s painfully slow when trying to access pics and articles. Otherwise I would post a link here. Tom
