Soundguy, Thanks for your comments. You can say that again. And doubly confusing when my Operator's Manual which came with the Dexta (I assume the original) is dated November 1964, marked for export and was printed in the the UK, shows a steering box which can be filled with oil via a filler plug on its side. But when I consult the Dexta/Super Dexta workshop manual it shows a different steering box with no filler plug.
Mechanics not being my strong point I want to be sure of what vehicle/steering box I am dealing with in order to obtain the correct workshop manual, and spares, for servicing the steering box. It looks to me as if this is a late production Super Dexta in which they installed a steering box from the upcoming 1965 Ford 3000.
I have the exploded view of the 3000 steering box but will feel more confident with the workshop manual. And wschaftl has kindly offered to scan the the rebuild pages for me.
Cheers, Charle
