If it's hitting on the lower (American) driver's side then there's no load bearing there and you could just grind off some material, no?

You're right Dodgeman. I was getting steering box mixed up with gear box (we don't use those terms here in the US). So feral probably did say gear box originally. Thanks for all the ideas. I'll probably try some combination of grinding and compressing that tube a little, or bend the whole thing if I can make up some sort of jig to do it. Hey Feral, tell the manufacturer to give a little bit more clearence in that area and they could more easily sell them here. Even with shipping it's cheaper than a Nismo header, assuming the exchange rate stays about where it is. Well, maybe not when you throw in the $50 western union charge but there may be a way around that (paypal??). Thanks again

That darn LHD steering box!
