Good drive axle with 12 tooth cogs from a 1981 Pantera. There are 2 slight imperfections on the splines where the sprocket rides as shown in pics 6&7. The sprocket slides on fine with no excessive play. SPROCKET IS NOT INCLUDED, the last 2 pics are to show that the imperfections do not interfere with mounting the sprocket. Online Cat parts lookup shows this came on:
