RH drive car, looking for remote oil filter options

Yes, that bolt is in a terrible position on RHD cars.
Best option if the engine is coming apart is to remove this adaptor, block off the centre bolt, then drill and tap the untapped gallery to 3/8”npt. Then remove the other gallery plug and you will have two 3/8” npt inlet and outlet ports that you can run some AN adaptors and stainless lines from. I’ve found that 1 x 150 degree and 1 x 90 degree -10 swivel works well, just make sure that the 3/8”npt to -10 adaptors that you get are as short as possible. Best way to then run the lines is between the block and headers just above the sump rail. From there I like the idea of a remote oil filter mount bolted to the chassis rail. Filter changes are easy then. Image of my block below shows the oil lines short circuited when I was priming the engine on a stand.
