After a good few months of searching I have finally got them.
Twin Dellorto 45s
SBD angled, wet manifold
And coil pack and modified distributor.
The carbs were on a 210bhp Corsa 20XE which had cams. They may need different main jets apparently as I don't have uprated cams, but otherwise are set up perfectly for my engine.
Pics to follow if I can get the bloody things to upload.
So now all I need is inlet gasket (on order for tomorrow), air filter (may not bother), and fuel regulator/pump. Then I should be all set for the pod on Sunday.
