Anyone recognise this aluminium upright? It is off a one off I have bought and as you can see is knackered. It would be good to know what it is from before I look at alternatives - someone mentioned saab?

Would say looks like a saab to me as well possible 93

Cheers Dick, I have had a look at 93 uprights from every year I can find but don't seem to come up with a match.

Anyone else any ideas?

Wheel bearing mounting looks similiar to a Saab 9000, but that uses an MacPherson strut.

If it is aluminum, could it be from a proper racecar, single seater?

Triumph has now been suggested but again not much luck.
It is definitely from a road going donor car I am told, just don't know which one!

On page 485 and further there are some measurements on wheel bearings, mabe the one that fits on your upright might be in there.
