Hi folks; Just a update, the engine is in, gearbox and rear end. We now have a 1992 Holden barina, ( suzuki swift, pontiac firefly ) and all is working fine. Wish it was street legal, but no our laws here are quite stoneage, electrics all work, and fuel tank undisturbed.
SO a V6 from a holden commodore does fit with very little work
