I went to buy a front outer cv boot for my 2006 Impala. All the auto parts stores and Chevy dealers gave me the same dimensions!? Here's the problem. The joint dimension is ok but, the axle dimension is to small. When I was online at Napa, they had a listing of different dimensions. The one I saw that I needed was for a 1995 Acura Lengened!? Both front axles are the same. Thanks for any possible solutions.
