ordered a Teleflex SH91800P TFX Steering Tilt Mechanism. Will report back.

Yep same issue I had.  This will sometime cause O2/emissions codes because leaks in the systems bleeds fresh air into the post cat sensor causing the ecu  to think there’s unburnt O2 in the system where it shouldn’t be. 

+1 on no fluid in the motor cavity.  I would think you will need to find that leak and replace that seal/oring.  Would probably need to replace the hydraulic oil that leaked out and clean the electrical side real well with electrical contact cleaner and dry out before reassembly and testing.

Likely you could get away with replacing just the midbass drivers. In each speaker as that’s probably what blew. 

The Rev's should come out of the cans, so you won't need new clamps, just the new speakers.  Of course if you go to 10's I think you will need new cans and everything.
