Drive shaft

[JonE]

So you need "just" the male splined part to fit in this (which will be a different size from other later Hardy Spicer prop splines) But you might be unlikely to find unless with a spare early UJ. Ring round the cherished suppliers?? I wonder if you could make a new one out of a more common early propshaft. (You are welcome to dimensions, but I suppose that bit will be hardened steel...)
