I finished riveting the doubler to the instrument panel flange (I really should work on the second one but that's in a different section) and then dug out various brackets needed for the fireall. This mostly consisted of cutting to separate and filing/deburring, countersinking, and attaching nutplates. This included the firewall bracket, the transponder bracket and the F-00054 brackets.
I've decided not to replace the center console. Too much can go wrong detaching the various cables and it looks fine as is.
