I fitted them to my 1971 13/60 and don't like them so will be going back to static belts sometime. I have MX-5 Tombstone seats though and think they'll sit better with standard seats. Other people have fitted them and get on with them better so a lot comes down to personal preference and probably the exact fitting of the retractor. You need Securon 514/30 with the adjustable retractor which needs fitting to the wheel arch. Lots of discussion and opinions where exactly this goes. Here's the Securon page on the belts - http://www.securon.co.uk/fitting/extras/514fitting.htm More discussion on this topic here - https://www.clubtriumph.co.uk/forums/topic/17843-inertia-reel-seatbelts-in-herald-convertible/#comment-193226 Good luck with the Herald.

Image of my 13/60 convertible boot. I wasn't registered in my previous post so restricted options when I posted.

I measure 60mm from the back of the boot, 40mm from the front and 430mm from the driver's side to the curve of the wheel well. On the passenger side the well just extends under the petrol tank. I'd post an image of my boot but can't see any option to copy one into the post.
