I was reading through a few threads about problems with latches going faulty and I noticed that Richard [GilbertD] mentioned that the door latches fitted to the MG F are the same as fitted to a 2001 P38.
I wonder, are these a straight swap ? But having asked the question here I see that they don't appear to be available any more. I'd be interested to find out whether they can still be bought. I will look elsewhere on the wobbly wonder web and see what comes up. I wouldn't be surprised if they are available, in LHD form, in the US.
UPDATE: I looked up the part numbers and, indeed, they are LHD car part numbers. So I think that probably answers the question - that they are NLA.
