Does anyone remember the part number for the Neapco upgraded u-joints for the TR6 and where I can get them? The Diablo TR6 project is about to begin! New JK Jackson comp motor, transmission, and Nissan 4.10:1 lsd diff. May the burnout be with me! Cheers, Jim Henningsen Ocala, FL 61 TR3A 62 TR4 75 TR6 81 TR8
