I don't know if a 74 is the same or not, but I did this recently on my 77. I did it by pulling the steering shaft out of the way since it looked easier that way. Plus the bolts weren't as crusty. Removed the rag joint bolts, 4 bolts on the firewall for the steering column, and 2 bolts on the dash for the column. I think that's all that was required. The hardest part was getting the new joint on since there's not much room to work in there. Also mark the alignment everywhere before you start pulling it apart or your steering wheel will be crooked when you get it reassembled.
