Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Don't believe you can interchange between models. I paid $205 for mine 2 years ago at Suncoast.
Frank, I posed this question to my indy when I had mine done and was told that they are not interchangeable... and the part was north of $400 up here.
They are different sizes. You might be able to fit old to new but not new to old.
Thank you all. I asked for a friend with a leaky 1999 tank. He thought we might be able to do it but in the end probably not worth the blood, sweat and aggravation. I told him I would ask the collective.
