My rating reflects the fact that the package states “for after market support plates Twin Cam”. That caveat was not mentioned in the on line description. <br />I have no way of knowing if my engine has “after market support plates”, and I don’t want to get into the engine to find out. <br />This might be a great product, but I’m returning it.
While repairing the rocker breather conversion I would quite the rockers down ass long as I was there anyway.
Be careful easy to bend make sure alignment is correct.
easy to install. motor is noticeably quieter.
Not really sure how much they helped but they are cheap and easy to install if your comfortable with taking apart your rocker box
Very happy with the results .
