So I asked L&N who they recommend:

Their reply:

Thank you for your inquiry. Because of the many different shops we work with and because a lot of shops do not buy directly from us but from a wholesaler, we do not recommend shops. I would suggest to you take your car to your current shop that you know and trust. If they have not done the job as of yet, they call us to get more information.

Sincerely,
