In response to loosening agents, try PB Blaster, much better than WD40 at loosening stuff. Better penetration. Available at NAPA auto parts and other hardware places.
out of curiosity...what would a top n tilt run me?
..as it turns out all i needed to do was get that nut out of the way. the way everything was painted and lined up...i had to get about 6" away from the darn thing before i could actually tell it was a separate nut and not just all 1 piece.

A Terrain Contour Control (TCC) TNT setup from Integration Engineering would run you about $1200. Check out Integration Engineering . Several TBNers have them.
