I was able to get the brakes on my 104 adjusted and working properly over the weekend. So the steering will be next. It works, but there is a lot of play in there, and also, it turns a much tighter radius to the left than it does to the right. So far, this is the only other neccessary mechanical repair. Everything else seems to be in good working order. After this, it will be all about wants and fun upgrades such as a three point hitch, ags and ribs, paint, etc.
This looks to be a very addicting hobby.
