You can also get them from Bob's Racing Things II at www.racingthings.com. Cost is $84 even, plus S & H. I have dealt with them for years and have always been totally satisfied. If you are going to Knoxville, they usually have a stand under the grandstand with some good bargains (just don't buy them all before I get there).

This is not a knock on The Sunday Hauler. I have also gotten a thing or two from then and had no complaints.
