I am not sure what you are asking for. All needed information is shown in the screen shot. It even has the correct syntax. You only need to copy & paste it into the mountlist.
Why do you ask for HDToolbox? You can only use either a mountlist or HDToolbox, not both(*). You say that the software is "pre-FFS" (whatever that means) so I'd suppose that the controller is not RDB-compatible and thus HDToolbox wouldn't be of any help anyway. Anyhow, HDToolbox of WB 2.1 does work on Kick 1.3.
(*) well, you could use both, but you have to be very careful to not create overlapping partitions
