I am not sure about MotoLita wheels but my Lecarra has a horn button. It too would not work with the stock adjustment rod because of the rods length. Also, it is imperative that the rod be kept in a tension state so the internal clamp can keep the steering wheel shafts tight. If not, the steering wheel will eventually, if not immediately, become loose. I wanted to retain the telescopic adjustability of the steering wheel without compromising the steering wheel and horn button integrity. So I took this approach.
First I got the adjustment mechanism to work correctly. Then I discarded the original adjustment nut (OK, I saved it in my Rootes junk box). I slid a 5/16 flat washer on the threaded rod then screwed on a 5/16-24 nut. I tightened the nut just enough to lock the steering wheel. Once I found the minimum nut tightness required to “lock” the steering wheel in position, I cut off the remaining stud. I then removed the nut and welded on two little metal ears about 1 1/2 inches long. This now allows me to adjust the steering wheel when I want. All I have to do is pop out the horn ring and twist the wing nut about one turn. Keep in mind that a properly functioning telescoping wheel adjustment should require only about one turn to loosen the internal clamp. It may be necessary to sharply tap the stud after turning the nut one turn.
