Just made some adapters for the mats with the larger holes
Found these spare at work, similar ones on ebay - http://www.ebay.co.u...=item27d967b60e
Skillfully hacked at them to remove the flange part with scissors , then opened up the hole from 8mm to around 8.5mm with a small cylinder grinding stone on my cheap dremel clone, 8mm will fit very tightly and a bugger to get off when u need to clean the carpet.
May need to chamfer the radius slightly as they do sit a little proud, all in all the mats no longer move about now
have 2 sets of 5 washers if anyone wants to do the same for their mats, you will have to modify them yourself tho, just drop me a PM with your address and i'll pop them in the post for free
