If you drill access holes on the underside of the top beam you will be able to use a T Bar allen key to bolt the extrusion directly to that quite easily.
Yeah i see your point, but its easyier than wedling it, warping it slightly then having to grind it off. once bolted its no hasstle to add a little tack weld that accessable for a grinder should i need it.

Good point on the hole on the underside of the beam!
