They look like this (but in yellow):
These are the 'short' harnesses so ideal for a kit-car or single seater (as opposed to a saloon or hatchback car).
They've only had about 250 miles of use but did do a track day in the torrential rain a few weeks ago so consequently are a bit grubby.
The retail for these would be £120 plus delivery and Yellow is only available as a special order which takes 3-4 weeks to be made.
Both harnesses are for sale for just £40 (collection from Huddersfield).
If there's no interest they'll be on Ebay this weekend as they're taking up space.
