Inertia seatbelts in a Mk3 Cortina

So you want to fit front and rear inertia seatbelts in your Mk3 ford Cortina? Well it’s relatively easy and here is how I did it!

The fronts are a simple straight swap but its worth mentioning that they should have a long solid buckle link as otherwise they don’t do up if you are a little on the large side and the inertia reel needs to function vertically, I just bought generic three point inertia seatbelts online.

The rears need to be a three point type but without the extra top guide so that the inertia reel sits on the parcel shelf and functions horizontally, they also need short webbing buckles.

Originally I bought some securon rear seatbelts which were apparently Cortina fit however the webbing on the buckles was too long so they fouled on our child seat. I ended up buying generic intertia seatbelts online and removing the top guides.

Seatbelt mounting holes are already there under the rear seats, the reel itself sits on the parcel shelf and bolts through the holes already in place. I also added some extra very thick large seatbelt mount washers for added security!

  1. Hi,

    I’m just about to fit seat belts to my MK3, where did you end up getting yours from because I’ll also be using a child’s seat.

    Thanks
