CTM x297 joints. They are used and some of the inner brass sleeves in the caps are getting worn. They are rebuildable but if you are running them in an axle that has manual hubs you'd probably be fine. I had them in a
D30 and it vibrated between 50-80mph. The website says $238.00 each I will take $200 for both. pm me or email me at danpascalept@hotmail.com Can get pics when I get back...
