As far as I know the bench bit isn't handed, at least mine doesn't appear to be. Worth looking into RHD anyway just to check. http://thelatebay.com/index.php?threads/late-bay-seats-bench-drivers.26946/
I would prefer you viewed the seat to make sure it's what you really want.. I'm in Wolverhampton. I bought it and then decided to go porsche 911. I paid £57 for it.
