So I am having a hell of a time finding ubolts brackets. I called etrailer and they showed me
these. I told the rep. not what I am looking for as I told them it was for 12 roller and bracket and they came up with these. I showed them the part I am installing and told them it was for a 3" frame.
Eastern Trailer have the factory ubolts and nuts/washer but do not have the bracket that has the same hole on center measurements. Went to my local hardware store Hyatt Builder supply and they had nothing I could use there as a bracket the would not corrode. Probably could use on the keel roller bracket ubolts but not on the bunk ubolts.
