...The top and bottom black edges that the endcaps screw in to are the same for almost any similar Mac, just cut to lenght. I'm 99.9% sure, the 2105 and 2205 blck edges are the same. I'm totally surprised Mac doesn't have them still.
There are many extrusion black edges available on audioclassics but i don't know which one will fit on my 2205. It seems to be impossible to get an helpful exploded view of the mechanical assembly of the 2205 (no answer from Mcintosh, audioclassics and tery)
