Those big caps do make a challenging mounting, I like your solution.
Did my old eyes spot that you used 3off, 25 x 3mm flat bars in parallel for the cap bus bars? I have used a thin smear of "Alminox" at all contact surfaces of alu busbars to prevent future oxidation and thus loss of contact area.
I also used M8 bolts to attach the power cable lugs to these bus bars.
Just a minor point but that alu angle at the top of the heat sink (fin side) would allow more convection heat moving up if it was flipped over so its horizontal part faces away from the fins.
