let's see what EC comes up with.If you are not satisfied with the response or replacement unit from EC, any local machine shop could duplicate the OEM part with thicker steel arms and the hole in the +25 length with little effort. Especially if they have the OEM and preferably the intact EC part for comparison and measurements.
It's just a tube with the correct I.D. for the bearings, then two flat arms welded in place with the correct spacing between the arms and the bolt hole at the shorter distance to give the lift result. They don't need to be exact in other dimensions. Some flat stock with two holes each piece and either a bit of tube stock or bar stock turned in the lathe.
But yes, if the replacement part from EC will look suspect to me, I will consider the option to have the OEM part retro-fitted with a thicker plate welded to it and the drilled with the non bearing eye a bit shorter. It should be relatively easy
