Thats what I´m talking about, some good old fashion "Why P-A-Y when I can D.I.Y." attitude. Go find some 3 inch tubing, and 1/8 in steel and weld up your own. As far as demintions go, if you are going to do it yourself, you better get used to using a tape measure. Take that bad boy and hold it next to the VAM and measure the disatnce between the holes, mark it out on the steel, center up the pipe, trace the diameter, cut and drillthe steel, weld up the tube and slap it on.
