That is probably what I will have to do. Do you have experience with this change? Does it keep the rear end up with loads and during hard acceleration? ( I would like to hit the strip at least once to see what it will do) And do you know of the best / cheapest place to get a set? Boy after all the time and effort of taking the old set apart, replacing the spacers, and powder coating them. Oh well. Thanks very much Pat. Larry
