Hi Its a Tamiya chassis and gearbox with a 80t motor the diffs have thick Grease to make them limited slip . moved the axels to correct distance and fitted extensions to rear axels to make them the right width. Bought a small scale model of dragon wagon to scratch build the body , don't try and guess the body I tried 3 times before buying a kit , its a doodle with the kit there are a lot of compound angles which makes it hard to do from a drawing.
