Old school 7/8" bar risers - Where to get?

[MX?]

Anyone know where to find the old type of bar riser? I've seen lots of the modern ones that have the two sets of bolts offset from each other, but I'm looking for the simple spacers that had the half moon at the base which fitted where the bars normally would and the opposite concave cutout at the top for the bars, then you just fitted longer bolts to clamp the lot together.
I need to get approx. 15mm in extra height.

just get 2 extra bar clamps turn them upside down on
bottom with long bolts through clamps on top

I got a set off Ballards in Sydney once they even had the longer bolts in the kit

Ballards i think still sell em. i got some on a TM there like normal bottom clamps but have a half moon bottom that sits in the old lower clamp.  would be easy enough to make some like Rusty says.  but im sure they still sell em.......

Thanks guys, yes Ballards list them so will get those.
Don't know how I missed those in the search?
I had thought of the upside down top clamp, but it looks a bit nasty.

I have got some if you are still looking

Actually I am still in need of a pair. Haven't got around to replacing my modern shiny ones yet!
What do you have, how much etc. etc.
