Thanks to those of you who have help me in the past. I have an 83-Ur-Q and 86-csq I plan to change the oil in the gearbox and the differential this coming weekend. What is the proper oil for these units and were can I buy it? Also, I intend to replace the brake fluid. Do you recommend a special brand? I appreciate your help. Thanks a lot. Tony.
