As the manufacturer of JBQ, I also recommend a 2-rail lift as pictured above. I personally have owned the Harbor Freight model, and it has served me well for more than 12 years without issue so far.
If (from the right side) you put the LH rail under the JBQ bracket, the RH rail will be under the sump, stabilizing the bike and lifting both wheels.
If you place the RH rail under the JBQ bracket, you'll only lift the rear wheel.
Thanks for your trust in JBQ!
