You're welcome, unfortunately I don't have access to Tracker part numbers, just Suzuki and they are not always the same, although in this case I suspect they would be interchangeable.
Whilst strong enough for it's designed task, the transfer case/transmission cross member is fairly easy to bend if you get "high centered" off road, it's not a bad idea to fit a skid, even if it's just to prevent catching the front edge on a rock.
