My question is this. The Torx screw locates the upper side of the LH side part of the bracket onto the outside of the heating system. Are there pre-drilled bolt holes under the transmission tunnel covering foam or do you have to drill your own and use self threading bolts?
I plan to install these even if I don't fit the dash pad and speaker as I have discovered the guy who sold the dash pad to me has cold me a pup! One of the end mounting screw locators is broken off and the center piece where the air vents sit has broken the plastic welds. I don't have time to fix it now so will have to stick the original pad back on.
Any guidance is appreciated!

Neil.
