I bought a second hand sandwich plate recently but it didn't come with the center nut. So i bought a center nut separately off of ebay to make it work but there is a gap before the nut closes up against the sandwich plate which leaves a gap. So I don't want to toy around and buy different nuts or washers or whatever, I just want to buy a kit that works. So I want to know WHAT WILL WORK without hassle or modification, that comes straight out the packaging. Can anyone point me in the right direction? It could be no name ebay brand, but as long as someone can vouch for it and KNOWS FOR A FACT that it will bolt up to the MSP oil cooler.
