CaptainFab has been making these for the larger diameter axles such as the 14-Bolt used in Gm 3/4+ Ton Trucks from 1973 to 1987?
Captain will know more specifics.
Either way, I have been asked by several members how I went about converting my 66 3/4 to a 14-Bolt.

I layout much of the 'How To' in my 66 Build Thread, but I figured I'd make a dedicated thread where others could ask questions and share experiences.
So, I'll layout how I did mine.
