Yeah, it doesn't look like they have done much other than some really cool body work.
You'd need to start with a series 2 chassis - i dont think there would be any other way to keep the lights on the grill.
move the firewall and engine back (could probably leave them in the original posistion, but a mid mount engine would be the go)
spend about 12 months full time building the front guards / bonnet :(
bobs your uncle.
