Hey all! Thanks huge for the varied input, from the sump lifters to the fabricators. I went the Fab route, and enlisted the help of my entirely too talented Dad, who has all the right tools. Saw a solution like this on another thread here, and will send some credit your way when I get off the garage floor test fitting! Piece of 3x3 1/4" wall box tubing, 15" long, cut in half with torch and cleaned up. Notched it to fit over bolts on jack arms, and then welded on two angle iron uprights, drilled two 21/64ths holes, and bought a grade 10 8mm bolt as a pin. This will slide perfectly onto one of the ATV lift arms, and a piece of 2x4 across the other to help spread the load. Now, to track down a spare pair of hands to guide the bike up for her first test lift! Thanks again all.
