mounting the new Vintage Air Gen 5 for 69 Camaro

[69C40Hx]

Vintage Air recently released a completely redesigned "Gen 5" version of their HVAC system for the 1969 Camaro. I was planning on using the Detroit Speed mounting bracket to install their previous Gen IV version but it appears it won't work anymore with the new Gen 5 since the case and basically everything else has been completely redesigned.

Just wondering if anybody has tried mounting the new Gen 5 with the DSE bracket or modifying it to work? Any other similar mounting solutions? I have a smooth firewall so I didn't want any mounting hardware poking through. I know the Gen 5 is probably too new but just wanted to see what guys were doing when they get their hands on it. Thanks!
