Adrian,
spring-loaded drop-head like the ones at the top of this page:

I assume the imperial sizing with 6.26mm diameter would still fit or did you manage to find proper metric 6mm ones?
Thanks for all the tips…. I am indeed going through the early stage of set-up and questions! Had a pleasant time last night fiddling and setting up some shock corded stowage straps along the sides under seats (attached to some points which I am pleased to say I remembered to ask Hartleys to fit).
cheers
Iain
