brakes arent too bad too replace.
bendix 4wd are the pads i run up front and highly recommend them.
rockauto (
https://www.rockauto.com/) has good stock of parts depending on your location. if anything will be complicated it will be replacing the rear drums and cylinders these can be picked up from most auto stores, shop around for prices as they vary quite a bit.
i am experiencing the starter problem at the moment, ill let you know how i go with mine, a brand new unit was going to set me back say $400 from a mechanic friend but im hoping to get it rebuilt.
clutch i have done before. wooders (forum member) was able to organise a clutch while he still had a shop front (not sure if he is still running his business,but he is a great person to talk to re parts). when replacing the clutch its painful but important to replace your cam and crank (as well as RMS) which sit behind the adapter plate. these are vitton seals and can be purchased through your bearing/ seal store. its annoying if your dont replace them as a time will come when the weep of oil turns into a leak and you have to do the whole job again.
as stated above parts sticky is a great place to start
