Just a reference thread for anyone that stumbles across this either now, or maybe even a couple decades from now. Lots of threads about the 7 inch LHD kits but figure I'd consolidate everything into one thread.
As of this post, Amazon currently has the RHD Koito part numbers for pretty good prices, if you're baulking at the prices other sellers/places are asking for the same thing.
If anyone knows of the part numbers for the missing LHD housing numbers (assuming Koito even sold them in the first place) please feel free to post and I'll update the table.
The Toyota RHD 7 inch H4 conversion housing kit is much, much more expensive than the LHD kit.
For Toyota part numbers you only need to order one; each kit comes as a pair of housings.
