Mike, love the work and welds.

I was curious why you mounted the filter so low - space constraints? having it at that level effectively reduces the oil capacity of the catch can as it will spill out of the filter if it ever reaches that level.

Additionally, if you do not foresee accumulating that much oil from the breather setup why was the box made to those dimensions? For a breather setup could you not have reduced the size in half and had the same results?

I cannot tell completely what how it looks in the fenderwell from the pictures but maybe you could explain your design strategy a bit more.
