The rads are offset to opposite sides to clear the steering gear which is why the hoses differ. I don't know about the lower hose but a LHD upper hose fits with a little trimmed off the length.
I see Rockauto now have RHD lower hoses. They didn't when I last needed one. They don't specify RHD on any of the upper hoses but pics of the Dayco, AC Delco and Gates upper hoses look like the one I used. The other ones look different so I wouldn't buy any of them based on the pics.
Found an old post. I paid £18.50 (about 2 yrs ago) off ebay for a LHD upper hose and trimmed 1 3/8" (35mm) of the rad end. Lower I got from the dealership but forget what that cost. Here's a pic I have that shows LHD/RHD upper hose difference.
