I beg to differ... I took mine off with a really long open end wrench on the bottom and a socket and ratchet on top... The nice thing is, the bolt doesn't fall out because it rests on the transmission, so it is easy to put back in :thThumbsUThe forward most bolt that attaches the seat bracket to the frame is the most fun. Gotta remove transmission to get it out!
These machies were built to last forever (when properly cared for) that's why it's so hard to get them apart! :ROF
