Hello Ladies and Gents, We are original owners of our 2000 205SSE with the 5.0 GL PWTR. In the past we have had the impeller changed by professionals. How difficult is it if you can follow directions? More importantly: What is the kit model # for this engine and what else should I purchase to complete the job? I'm at the stage where I want to learn these things, but the problem is that I can't easily find kits in my version of engine... Prod#3868944 SN 4110197071 In advance, thanks for your help!!
