It is from a RHD car,,and usually the one that breaks.
It is in excellent used condition.

From there, you'll need to cut out a piece of masonite or other hard board (use the LH one as a template) cover in foam and cover that in vinyl. It's actually pretty easy. Probably the harder part is sourcing the three screws. They need to be long enough but not too long that they can be felt coming thru the foam.
