Tb plenum help

[No1893]

Hi Im new here but don’t have a mustang. I have a syclone. Catch is Im struggling and need some help with my build. I’ve exhausted every search possible. So I’m hoping someone can help me here. We don’t have many options for intakes when using 23 degree heads but Im using a brodix b90 with a 4150 flange. A 75mm throttle body is perfect for me so I am wondering if someone can give me some ideas for plenums? I haven’t been able to find a 75mm-4150 plenum or an adapter to go from 75mm to a 90mm either. Any insight would be much appreciated. Thank you
