Try contacting Bomex too. They do not sell the S15 conversions but they can hook you up with some custom stuff if you ask. There was a site that sold full conversions but I cannot find it!!! I was just looking at the site two days ago. I want to say it is boostdyamics but there site seems to be down. If I find I will let you know and when you do the conversion don't forget some pics! Good luck
