g60 patrols are so old - I have one in my back paddock that I cant even give away.
G60 went to the mid 70's and the design did not change. Heavy chassis, rust prone body, drum brakes that were undersized from day one. no power brakes or power steering, noisy, so dont bother with a radio, and they all leaked like sieves? You can buy replacement bodies, adapt some gu running gear and a v8 holden moto if you are doing a project, but they are very heavy all the same and expensive to fix. I would suggest a landcruiser shorty if you have a choice, and if all you are buying is a pair of diffs and a chassis, you can have mine for $500 and mine has a $2000 fibreglass upper body installed?
