There are several places that I bought badge “brackets” for the badge bar. One was Moss Motors (http://www.mossmotors.com) and the other was Triple C (http://www.triple-c.com)
Most kit car badge bars are from Marine applications. They are made from deck rail hardware. So, they are not the standard diameter of the “authentic” MGTD badge bars.
Another thing is to use stainless steel hardware that is readily available from marine Suppliers.
Good Luck.
