the dealer dicontinued the spindle around '96. i dont know about the caliper brackets or brake hose brackets. the rest you can get at a parts house except for a metering valve and prop valve.
for hose brackets, you could make some, or i think they are available thru classic or ames.
a salvage yard is a good place for alot of the parts, and some of the parts from later years will interchange. it is also a good place to pick up caliper cores, even if they are not the right ones, they will work as a core, and save you a few dollars.
do alot of research before you start. you should be able to save at least a couple hundred over a kit. there is a bit of info in the FAQ section on this site too.
there is alot more stuff i would like to include about lines, valves, fittings, and other specifics, but this is enough for now, and might be included in the instructions Doug has.
