Well, Unless you're in UK, this is the shelf for Driver's Side. Part Numbers in a post way above.

 

I got my driver's side shelf from Rasmussen MINI when I picked up my MC. They didn't order the mat, so I went down to Home Depot and bought some perforated (large perforations) rubber shelf liner (comes in various colors- I got black) made by Magic Cover called GRiP EXTRA- it's very stretchy and has a nice thickness. Cut a piece to fit, put a velcro tape patch on each side to stick it down, and it keeps things from sliding. I even cut a couple of strips for the bottoms of the door pockets to quiet the stuff that I've got there, though I don't know how it'll work out in the long run- time will tell. The only rattle I want to here is my passenger's teeth on tight radii run right- MINI style!!
