Where to buy manual steering box seal kit?

Ya know, I had play in the steering of my 64 Signet for years and was looking to buy another steering box but one day with the engine removed I was fooling around and realized it wasn't the steering box at all, it was the steering coupler and when I rebuilt that part for 20 something bucks, the steering was perfect again

Someone in another forum just pointed out to me that mine is a RHD and they might be different compared to the ones for LHD!

Here is another picture of my RHD manual steering box


Does it look anything like the ones you have on your LHD darts? Just making sure...

Thanks again.

PS: Australian shops: Rare Spares only sells Ford @ Holden stuff; Mopar Market has none for RHD valiants/Dart; and Blue Star does not have any either.
