Absinth
We would love to produce the thicker spoke wheel but when you are advised by a Government body and our own legal team not to, you take their advice.
For your information all steering wheels must meet ADR10, you will find that HK HT HG wheels meet this ADR; it has nothing to do with the year the part was first made.
As for the gear shift knob I assume you are talking 4 speed part number 2817736 if so it is listed in the HQ – HZ books that I use, although it is superseded in the HZ on to 9946729 in later HZ’s.
