Hey Maurice, Blue Ox doesn't have a torque spec recommendation for the U-bolts of the Immobilizer part # BX88224 that you referenced and instead they just state to "tighten the whiz nuts firmly". Which if like me you didn't know what a whiz nut is...it's a flange washer that is serrated on the bottom to resist backing off.
So basically using standard hand tools just get them tight and you'll be good.

Hey Maurice, did tightening the whiz nuts with standard hand tools work well for your Immobilizer? I'm curious to know if this solution was effective for you, as it could help others in a similar situation.
