Ok, measured it for you. The front crossmember width is 24 inches, and the rear is 30 inches. If you are going to build your own frame, I have a suggestion for you. The 2 and 7/8 inch diameter tubing you need for the front crossmember is hard to find. Total Performance sells a 23 3/4 inch piece of it for $ 25.00 already cut perfectly for the front crossmember. You can get it with their perch too, if you want. Some people use 3 inch water pipe, DON"T DO IT. It is not made for these kinds of stresses, you want DOM tubing, and that is what Total Performance has.

Tech's suggestion about the National T Bucket Alliance is a very good one. Lots of info there.

Good luck.
