Second on the Caddy horns. Just go to the yard and pull them from an old Eldo or Fleetwood (older the better)

I did this for both the Subaru and the BMW

Here is a tip, take the original horn wiring and put them through a heavy duty relay and then run a large wire from the battery to the relay to the horns.

The wiring on the Japanese cars cannot handle the load a set of big DEEETROIT horns puts on it.

I don't think the MBs can handle much more either. I have had the fuse blow on me twice when I laid on the horn while the rear defroster was on (same circuit). I've heard of folks turning old AC compressors into air pumps for both airbag suspension and the always-necessary train horn collection under the hood.
