I purchased the RS Assembly locally. You can also find out of state Ford dealers that will undercut other dealers on the bay. No honor among thieves I guess.I haven't had issues yet, but am thanks to your heads up proactive guide, I will be ordering parts to replace and make future assessment easier. Tasca has the RS assembly mad cheap, but almost cost the same to ship it, so unless you have other items.. I have found Amazon has it prime shipped, under Tasca total price.
