Old Leafsprung Land Rovers

I've not got a decent photo, I'll post one tomorrow I think I've a piece of one piece seal still attached to the tub or side panel.

I'v just had a search for tube rivet tools and found this place.

Not to far from home and not to pricey. Would work well in a G cramp type tool, should be able to squeeze in a controlled manner.
