So I used the Lares kit with just the rubber disk in it to do my rebuild. Here are the problems.
1) The Rag joint listed for sale from vendors is for 1970 and earlier. They had I slightly smaller steering box side coupler. So it will NOT work on a 71 through 73.
2) Unless something has emerged in the last couple of months, there is no replacement or refurb for the 71-73 rag joint. When I called Lares directly, they said that they were working on one, but they did not have a release schedule or date.
3) Any kit you buy with a rubber disk to repair yours comes with hardware that bolts together and is designed for the non-tilt rag joint. So I spent weeks trying to find rivets to duplicate the original rivets, or shoulder bolts that would work to no avail. I used the provided fasteners and got it together, but I am unhappy with it and check the fasteners often.
I even offered Lares money to rivet a new rubber into my coupler, they said no. I asked if they would sell me the rivets, they said no.
Borgeson is another one to try. They had the same responses.
I used the Lares kit from Advance Auto. I can't find the part number at the moment.
