What is the best base/attachment point that lines up with the pre drilled holes ?

The back of this device has pre-drilled holes that are designed to be used with other RAM mount accessories such as the Ram Mount RAM-B-138U Double Ball Flat Surface Mount

U-bolts are a good method. You also might want to drill a hole thru poles both and insert a long, locking bolt w/nut to avoid minor movement in windy conditions.

It is not pre-drilled and requires you to center and drill. I would highly recommend the centering system sold by Rousseau here on Amazon for $6. With the kit the drilling is fairly straight forward and simple.

The holes are predrilled and not the same spacing I believe if you switch corner supports during assembly will result in what you want

It dependents on what detachments and the depth of their attachment --without specifying what you want to attach that's the best answer I can give.

I've bought these from at least 2 different vendors and they have not. Just the 2 inch base as pictured. The holes are not concave or conical, so you can use small bolts or drill it out to use screws.

Almost any action base "should" fit. It comes with a connector and you may have to cut the round peg off one of the adapters to fit the square attachments. But normal bases will work as long as your willing to modify

simply drill matching holes in the correct size needed. most hardware stores should have short pieces of flat stock ,in many sizes. re use the same screws.

We used 1" Phillips Head screws. My husband put in 4. He can't remember if the holes were pre-drilled or not. Either way the screws make it solidly stable. As he recalls it was really easy. He doesn't remember if the tabs were a problem; however, if they were he would have done the screws anyway...

With the drill, I would recommend pilot holes. If you get the impact wrench, no need for pilot holes.

The mounting holes are on 9-3/4" centers. You should use flat head screws, #8 would do. Adding a flat washer would be good. The type of screw depends on what you are mounting the box on.

Make hole with step drill bit or find a drill bit close enough so it can fit being verry careful then add glue after light is where you want it to be. Thax :) you is the man:)

I think that is what i have. Worst case is you deill a couple of extra holes to line up with your base

I lined the base with 3/4" plywood (as there are plenty of holes to bolt down, then bolted my machine to the plywood. This gave me a bit larger base with more stability.

Any flat base should work. If the base isn't level the doors not be aligned properly.

I would make a template of cardboard first then punch holes for mounting points. beauty is you waste nothing and find the best mount points for your bike and like before it has been said use zip ties.
