That car was built by Home Grown Hot Rods over in the UK near you, maybe inquire with them? [email protected]

The Charlie Price post is not correct, but the Home Grown Hot Rods one was. Charlie's are not the same as the ones in the OP's post - his are cut at an angle to make them look like the original Thickston ones - i.e. they are not the same height front and back like the original ones that were from the UK in the OP's post.. http://vintagespeed.com/wp-content/uploads/2012/02/chrome-3x2.jpg
