As Ruben said the Veeder Root support bracket is an easy fix for anybody that welds, most likely cheaper to fix than replace. The T36 does not get parted out much anymore so the parts are hard to find and not cheap, if you can't get it repaired I can supply it.
As far as your visi gauge support casting, all I see wrong is the pipe has been cut off and that is a real easy fix, or maybe I am not seeing something or you don't have one and this is just a picture for reference. To get the pipe out, just take a Sawzall blade and cut thru the pipe in 2 places, 180 degrees apart and knock the pipe out with a chisel. It doesn't matter if you cut into the casting threads a little, you won't be pumping gas thru it I wouldn't think.
