BH63, it is almost certainly a Trailblazer as claimed in the ad. It has the correct top yoke, a type only used on the Woodsman and the Trailblazer. It is unlikely to be a Woodsman, because they did not have the longer swingarm seen here. The Apache had a twin clock top yoke, and also only the short swingarm. If you need a speedo for your Chief, Hitchcock's have one for sale, look in the used parts section on their website.
RGT, your 2002 will bolt straight in. The only engine mount difference on the later frame is the absence of the saddle tube and triangular plates bolted to the top of the gearbox. This arrangement still works OK, but you may like to add the stiffening fixing used later on the Interceptor. This is a simple mod, consisting of a cast alloy bracket bolted to the back of the gearbox (longer studs required) and to the swingarm mounting plates.
