There is a plate version for the 4 string basses, but these are not suitable for the 5 string, which uses a larger plate. For the 5 string, the non-plate Marcus Retro can be used, fitted to the existing plate. The knob spacing for the 5 string is slightly larger, requiring the holes to be modified slightly.

Also, if the Pickups Toggle is to be installed, then an additional hole will be required.
