Oldest baywindow?

And front beam I believe is one year only or maybe same as a late splitty beam?

 

Beam is 68/69 I believe. Mounting points are in the same place as a split but I think splits were all k&l? Not sure what you mean about the breather pipes. Definitely not there on a 68

 

I thought late splits were ball joint, but I'm no anorak.

 

As far as I know 68/9 beam is different from a splitty beam - it certainly was for the one I bought in error.
