My shorty has drums on the rear and coupled with muddies, its shocking to brake in the wet.
(compared to the LWB mav which has discs all corners).

Has anyone done a disc brake conversion to their rear end and if so what $'s can I expect to pay to do the job....

I assume that I'm looking at a GQ/Mav disc rear end and a diff master cylinder?

master cylinder is the same.
before you do that make sure you check the system is bled properly and that your bias spring is set correctly.
Got drums on a LWB and they aren't too bad, can lock them up when I don't set the bias spring correctly.

are you sure about the master cylinders being the same??? as when i replaced mine a while back he asked weather disc or drum and said they were different. had a different bore size. or along the lines of that but they were different.
apart from that its just a straight bolt up. but you will need a new complete diff housing with the correct ratios and discs on it. then just bolt her up and away you go.

Hi,

There may be a residual pressure valve in the master cylinder that will have to be removed. I did this fitting discs to a car 25 years ago.

I believe they are the same, but the twin piston front calipers DO have a different master cylinder. However if there's any doubt (which there is) you should check.

Residual pressure valve in the master cylinder rings a bell.
