Rocky Mountain Dashes??
I did this right hand drive dash using 3 mm aluminium, never welded aluminium before and to my surprise found it hard to weld through this thickness - and I am a hack welder, no doubt (I wont show you the back of the panel!). So dont be afraid to give it a try.
I did the bends in a vice, crude, but still came out fine.
Had a RMD made up RHD but it looked too "backyard" for my taste, wanted something with more of a finished, factory look.
