If you are after shortening the shaft on your Sim Jack Shifter try this out, it drops the height of the gear knob to bring the length down to more like the Heukensveld shifter. 100% non destructive to your kit and easily removable (you may need pliers to unscrew it its quite tight) simply screw on as shown in the video (metal threads should not poke out of the top of the adaptor), and thread your gear knob on to the adaptor and you are good to go stop tightening when it is on firmly, if you keep tightening it with great force you will destroy the adaptor, it does allow plenty of tightness for

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as SIM RACE MODS LTD., number 15496219. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
