2002 American Tracker

My estimates I am studying mechanics at a trades school, I have an American 2002 tracker, a mechanic recommended changing the distribution kit and I bought one here in Villahermosa Tab, and I have problems with the tensioners, and I have asked about the original kit and I can't find it, they could help me because the truth no longer does not know, and I would like to sell it but I will not help me and not sell to me. Saudações a todos
