This works, but it won't thread on far enough (at least on my truck to totally seal with the o-ring they give you. If you use a thick o-ring that comes with a normal oil filter and leave that tiny one in the picture in the groove (or don't, I don't think it matters) it will mate up perfectly. Since you never have to take the thing off, after I tightened it down I put some grey RTV around the o-ring. Never leaked a drop for me.
The big filter O-ring trick doesn't make me feel sketched out by doing this either, as it mates to a flat surface on both sides and doesn't come into contact with the groove on base of the remote mount and you can definitely get it plenty tight that way.
This is where I got the base for using that giant donaldson filter to mount under the frame rail..
