Just bought a used 2005 r52 S.

The previous owner did the absolute worst aftermarket rear speaker "upgrade" of all time. in doing so, he removed all of the bolts holding the rear seatbacks down (4 front bolts and 1 rear bolt), and also removed whatever 8 (4x2) smaller bolts attach the OEM HK speakers to the metal chassis.

Does anyone know what bolts are used in both of these spots?

Looks like #4 top diagram is the mount which the btoth centers of the upper seats hook into. See if bracket has a hole on the backside.

The top one pic, does it have a thread ? I thought it was a push rivet, does the carpet have a hole there.



I would inspect the whole rear for missing parts as now you have the diagram.

Wow! Fantastic response. I'll rip apart the rear this weekend and see what isn't there.
