Pocket stop retrofit

This is my first post on this site. I am also on the pop up times website. I have a 2006 Fleetwood Santa Fe. I recently purchased a 2000 2720sl. I read happy trails very informative post on adjusting the pocket stops. Mine still has the shims. I was wondering if anyone has had their T.M. retrofitted for easier ajustment? If so, what was the cost?
