Rear Seat Belts fitting in a 1973 250?

[diver1]

Hi All! I have just bought a 1973 250 saloon which I am very pleased with. Ideally, I want two reel inertia seat belts fitting in the back.

Does anyone know if this model has anchor points already available for use?
Is anyone aware of a reputable installer in the Shropshire (or wider) area?

Any info would be greatly appreciated.

Cheers, diver1.

Rear Seat belts

Hi,
Pretty sure all models from about 68 on had rear seat belt points. Unsure if inertia reel type can be fitted.
