For the watts link, is it diff pivot style (Cortex or Griggs) or is it frame mounted (BMR or Shelby)?
And as far as the issue with diff cooler line rubbing I would look at your LCA lengths. With a watts like you want the LCA's to be around 17-7/8" to 18" in length C2C, if they get much longer than this you will start to have rubbing issues with the watts link pivot and other body/suspension parts.
