Trimble / Bobcat GCR Upgrade to Bobcat BLR2 or similar - Is it able to be done

[cwbyup]

Hello everyone,
I currently has a Bobcat Box blade that was originally built with the early laser system (pre 657500367 serial number) that used the Trimble GCR laser receiver.
I dont have access to one of these in Australia so was looking to see if I can get a BLR2 (still hard to get in Australia) or upgrade to any other style of receiever ?

I have not been able to find much info on these systmes.

Any help or ideas would be appreciated.

Is that what had or was using? How did the system work,was they a monitor in the cab, I run Trimble 2d with laser catcher. There is a monitor in the cab that shows me what I need to cut/ don't confuse this with GPS.
