Keep up the good work, are you going to delve into the drivetrains at all? One thing I would recommend checking, cleaning and repacking are the two steering idlers left and right. These house two tapered roller bearings and adjust much the same as a wheel bearing, mine had almost been welded together by very old grease and once cleaned, repacked and adjusted the steering is not to bad. The wife drives ours and has no problem, however, has not driven it in Safeway car park yet.
