to make the sled more narrow so that it can fit into your stock radio harness? I'm thinking about replacing the screws on the sides of the Empeg with flat head screws (after counter-sinking the holes). Then unattaching the side panels from the sled, file down the side edges (roughly the height of the original screw heads), and then reattaching the side panels? This whole process is something I am considering doing so that the sled fits into my car's stereo cage/harness. I can't alter the stock harness and I can't buy an after-market one either (because the front fold down facia mounted on both sides of the harness seen in pic). The only other option is to not use the sled, and cut off only the rear panel of the sled and mount it at the rear of the stock harness. That way I'm using the harness and the top of the after-market CD/radio as an Empeg "sled". By the way, the car I have is a Subaru SVX.

Thanks,
