Just looked - your right they're near identical!

But I assure you mate - I know nuffin about it - I really did build mine by hand (got loads of build photo's in the cars protfolio) and I know waht you mean about trying to find the valances - I was lucky with the rear one and got it off a white cabby in a scrap yard a couple of years back, but the front one took ages to find, and I had to settle for one actually designed for an Orion, not an 88spec front bumper - loads of cutting to make it fit belive you me, lol....
