I bought the new rag joint I was just curious how hard its gonna be to swap in the new one. has any one done this recently that wouldnt mind explaining it to me in detail, or maybe a link to how to do it. Thanks guys....

 

I have never done a 1978, if it is like the older or new ones, you take off two nuts holding the steering column for some play room, go under the hood and remove two 1/4" bolts holding each side of the UJ to the steering shaft, slide the new one on over the splines. Note, some steering set ups only have one bolt. Then reverse.

Spraying some PB Blaster down the splines might not hurt.
