A friend of mine in the Denver area has a mid 80's Blazer that wanders and she needs to have the problem dianogosed. It should be real easy seeings how us wheelers pretty much have to do that every time we get off the trail. If there is somebody in the Denver area that could help me and her out that would be great. I'm in california so it is a little tough to do anythingfor her.If you can help please call 916 955-2950 [Glenn] or post a number here that I can get ahold of you. THANX
