I put a set of these in mine:
However, they aren't going
anywhere as far as sliding forward or back, but not only that, they squeezed the console area so much I had to cut the inside of the console in half to fit it back together. The top fit fine, but I just couldn't get the insides back together.
I paid something like $200 apiece for them I think. They
are very comfortable and do hold you firmly in place.
