ZF Steering Box

[Thor]

I don't think the ZF steering box used on Bristols is a rare type. In one of the few conversations I had with Tony Crook myself, he told me he was amused by how many ZF engineers came over to help with trying to adjust the valving to achieve more steering feel. He said he thought they may have been disappointed by the relatively low quantity of subsequent sales. The conversation arose, I think, because my 409 was the second Bristol car built with PAS.
