I'm sure I do. What's your budget as I have anything from a new Thompson to used others.
I'd recommend something long enough to give you the height needed to ride, and a fair bit inside the frame. Posts that are too short will result in the frame potentially getting damaged and could result in it breaking. Something long enough that once inserted, goes below the top tube lower weld at minimum.
I'll see what I have.

I'd suggest 2 inches below the lower weld on an older aluminium frame
Great, thanks!
If you are interested, drop me a message.
Ian has very kindly shared photos and dimensions of bushing/bearing stuff for pivot.
A new set of the main pivot top hat bushes, still in packet.
And then there's the bearing side of things.
The two bearings with the centres that rotate/can be angled (can't remember the name for them) and spacer that sits in between them, do the same job as the main pivot top hat bushes.
There are 4 bearings in the rocker, 2 each side.
Measurements in the pics will be close, though there is a margin for error as the verniers aren't the most accurate, but should be close enough.
