Steering wheel options for us Early A drivers

ok last update: want to first clear up, the issue is beneath the hub, not the horn button. The main issue is, the install kit hub is going too far down the shaft when screwed on fully. So far down that the contact plate (that touches the roller) rubs against the turn cancel assembly including the hex screw.
That recess in the shaft can not be filled with anything as the hub slides all the way down, past that recess. Grant did send me 2 pieces of tubing (I emailed them my problem). You will see in my pictures. I used the longer tube which basically is a piece of pipe, slide it all the way down the shaft. It rests on the C ring, which is now my concern. I am afraid if I now tighten the steering wheel nut too much, it is going to push that C ring too much or break it? But it is working now, and it gave me the extra space so the contact plate is not hitting the hex screw. I can now use turn indicator without getting a Beep.
Thanks for all the ideas and help.grant adapter - 1.jpggrant adapter - 2.jpggrant adapter - 3.jpggrant adapter - 4.jpggrant adapter - 5.jpg
