Got shafts back this afternoon. Took the pros a couple of hours. Installed 3 Napco's and 1 Spicer because they could not get the 4th Napco in a reasonable amount of time. They were surprised thatI was having the work done because the joint s were not in bad shape. The centering ball kit was number RF404-0A. They matched in house to the shafts and joints. Total was 216.00 for the joints and centering kit and 60 of that was labor.
