In another place (sounds like the houses of parliament here), someone has said they can't find schumacher rally blocks, I think that's because they're not actually called rally blocks.

Do a google search for either the part number or "sst rally" which should come up with the right things. If you only use the part numbers, put a comma afterwords and "-hoover", so "U6630, -hoover" as it's a hoover part number too.
