I am having a problem.  I was sent the center leg support with may original order. Item 3.  It was to long at the same length as the side supports.  You have now sent the replacement part and while it is the right length now the dowels to insert into the legs are to big. It was clearly meant for a different hole.  If these are milled as a unit, do you have to send me an entire new leg set.  I don't know but I am very upset at this point as I have built this chair twice now and still can not complete the assembly. I need the correct part and I would like some type of credit for this continued issue. In the picture the replacement piece is on the left.  You can clearly see the connection dowel is much bigger.
