I have a pretty trick setup.
I started with this.
It is basically a few pieces of sprinkle/electrical pipe and the piece of plexyglass which you could buy at home depot/lowes. There might be $12 worth of parts in that "kit".
Its a good start it you don't feel like buying a large piece of plexyglass and cutting off a small piece.
I then bought a few pieces of pipe and another pipe mount. I drilled a hole in the pipe mount and bolted that to the floor at the seat bolt. and bolted the other to the shifter console. then used the other pieces of pipe to connect the two and a "T" fitting to mount the plexyglass to. I have a manual tranny so space was limited. I take out the plexyglass piece when i am not using it just to have a little more room.
It works. if you go this route loctite is your friend. My setup was very loose and the whole thing would move around some. I took all the piece apart and loctited the crap out of them and now is super heavy duty fixed in place.
Those kits on ebay were about $20 when i bought mine and i think i spent another like $10 on other stuff extra pipe, extra velcro and stuff. So for $30 and not really having the room with the stick in the way i am very happy with it.
