Strengthen the b post? Argh, hope not! Got that rather than just the lower bit because it’s knacked higher up, not just at the bottom.

But I’ll use as little of it as I have too.
As for the inner part of the b post, I think that’s only rusted at the base so I’ll rebuild that (and the j.p. reinforcement) with bits of sheet once I’ve got the inner sill on, and can see how the outer b post meets it. Sounds simple, eh?
The bit with the label is the strengthening piece above the rear jp. Comes down vertically to the edge of the inner sill, has a funny curve in it. Here’s the top part behind the bolster.

And here you can see the lower part behind the rusted away c post and extending forwards towards the camera.
