After reading this I went to get a 6 pack rack for the old lady's warrior, turns out the local shop had an ac racing one , it also had the tail light mount. I figured piss on it , and got it, fits good and looks good, no complaints. I also have an ac on my 89 banshee that fits good. Oh, yeah , I have used AC aluminum subframes on my KX without a single problem , other than them bending when I high side in 4th gear.
