Transmission to Exhaust Mounting Brace Hardware?

Trying to make sure I got everything and I'm not sure what I need to hold this part to my next pair of test pipes/car.



Going off this diagram, I'll need 20606 x2 + 20652M x2, and 20030B x2- but what holds 20030B? Do I just use more 20606 bolts and everything snugs up? (It appears Z1 Provides 20610 rubber bushings). Unfortunately a shop removed my factory brace because of how rusty and ruined it was, so I never got to see how it was mounted.

The brace, 20711Q, uses the two 200308 nuts to connect to studs mounted on a bracket that is part of the OEM Cat. Most likely the test pipes won't be designed with this bracket and will not be compqatible with the brace.

If you go to Ebay and search for a set of G37 OEM Cat's, you will see where the bracket and stud are located. Also, you can look on the Z1 website for the Berk HFC's which also show the bracket,

Did some searching, I think this might work. Maybe I'll get a washer to stabilize it.
