Mine went on in less than 3 hours (Q-tec 9000) on the stock bumper, which I needed for towing behind my MoHo.
Very pleased with the install, but couldn't use the stock, or aftermarket D-rings, due to a weird hole mismatch. 1/4" off moved the mounting plat by 1/2 " forward!
I'll figger out the geometry and report on it later this week.
I know that this is a very popular winch, and Q-Tec is ready to help me with my problem.
It has something to do with the factoy mounts, during the transition,
The winch is on, but looks a bit "hinkey", setting over the factory mounting bolts.
I know I won't have any problems with shear, but what If I need air support?

Did it all myself, made every mistake possible. Fixed it all here
