Can anyone tell me if there is any info available on repair/refresh TRS drives for the do it yourselfer ? Books , Videos . Need to know whats been learned over the years to help them last other than the ovious. Have ability to understand backlash, gear pattern match, crush collers, indicaters stuff like in a 9'' FORD rear .Running less than 600 hp twins . I know Konrads are the answer but wont be in the buget this season! Also who to trust to do the work if I have to send it out and around what price? I have 4 drives 3 need gone thru and set up . 1 needs lower gears as well, case is OK then they need powdercoated or painted. Thanks Dan
