Yup. I don't recall exactly what I had to do to make them fit (that tank was done a few years ago) but I don't recall it taking that much work. Flattening off the back of the top and bottom plate, as they don't fit into the door frame the way they do on the Raider... I don't recall if the mounting post for the weapons had to be shortened, but I don't think so.
The biggest job was just converting the twin lascannons into singles. On that tank, they were magentised so they could be swapped out for heavy bolters...
