The A-C B uses a 24" rear rim. The weights bolt onto the nearly flat center with 2 bolts that are at least 1/2" in diameter. The bolt spacing is 14.5" as I measured it. There are four small notches in the edge of the weight for clearance on the rim clamps and 2 large u-shaped notches for valve stem clearance. If the hole spacing on your N-series wheels matches, they should work.
