Strong endorsement for the change. I believe the Mopar part number is P5249644. A quick google seems to confirm it: (i have no affiliation with this site): ~$167, or gbp 120 plus shipping.

I have been very happy with the result in my LHD 410. It was fitted at Bristol in early 2002 and has been only lightly used since, but works very well.
Warm regards,
Steve.
