motor, if gas is a standard 134.. parts available.
3pt arms.. can be made or modified.
tie rods? if working.. forget for now.
car tires? leave em till last if they hold air.
bad rear? look for a matching used one.
rims? find matching when you can.
rusty tank? clean, coat or replace.
steering wheel? not a problem..
steering box..... that's the one I'd put my effort into.... the rest of the items are routine and realitively non issues.
