Does anyone have the original link saved? I looks like the fatter lower nipple needs to be ground down or ground off. Also, the MKIV mount does not fit into the black metal fitting that goes under the block mount bracket. The MKIV mount is as tall as the mkiii one without this bracket. Should I go without it or make it work. It is part number 12381 here http://www.cygnusx1.net/Supra/Library/EPC/291420/catalog.aspx?Figure=1107&Page=2 .
