Early and late 3 point linkages are different. I don't know what year the change over came about but the big give away is the type of axle casing that you have. The 3 piece casing is the later type and the early axle casing is one piece.
I did a bit of digging around on the net and found a company who can make up the steel pipes with brazed banjo ends. So when I have some spare cash I'll be heading off for some of these.

I bought my 3 point linkage new. Its a very good reproduction of the later type that I needed on my 1965 411.
