Well I don't know what the dimensions should be but I do know that swapping 
front beams is a back-breaking job. The complete assembly is heavy and 
awkward so I ended up taking off the trailing arms anyway, just so I could 
get the beam lined up with the holes in the body. If your existing beam is 
OK, leave it well alone and just swap the arms. Now, all you need is a jig 
to check that the beam is straight :-)
