Adapt Modern 3-Point Seat Belts

The stock 240z seal belts were okay back in 1970, but they're awful compared to modern belts with a retractor. You can buy aftermarket belts that are supposed to be an easy upgrade, but they come with some disadvantages.

You can do it yourself at a fraction of the cost, but it takes a fair amount of time and access to a welder.

Here's the process.
