Really.. Dont be in a big rush to pull a perfectly good truck apart. If it "runs and drives perfectly" as you stated, thens whats the rush? DRIVE IT AS IS. Get a feel and liking for what it was in the begin with. If you need togo 90 mph down the hiway all day, then find a different vehicle to suit your purpose. Give it a minute as it is, you might justl like it?? JMO
