I've had plenty of them too. At one stage there was 4 x pairs in the shed, 2 x pairs from Kingswoods, 1 x Deville and 1 x Caprice. I think there is currently 2 x Kingswood pairs up on the mezzanine, although from memory I used the runners off one pair on VH Calais seats that I put in the Overlander before I sold it. When you compare Commodore and WB runners side by side it isn't that hard to modify them to be the same, just needs a tab welded on each end from memory, and when you do it make the tabs a bit wider on the tunnel side runner so you can capture the factory HQ-HZ floor nuts.
