Sorry, but there is no SAFE way to put 4 or 5-point belts in a car without a cage. Has it been done? Yes... but it is in no way safe.
Unless the shoulder belts are mounted at the same level as the shoulders and passthroughs in the seat (+/- 10 degrees or so) there is a strong risk of spinal injuries should you ever be in a crash and need the belts. Excess belt length (such as what is seen when guys run the shoulder belts down the back of the seat and bolt them to the floorpan behind the seats) also leads to additional stretch in an impact which prevents the belts from doing their job properly.
Not to mention with 4 points your torso is kept vertical in a crash and without rollover protection your head becomes the rollbar. With a standard 3-point your torso is allowed to bend inwards and clear the now caved-in roof.
For a car without a cage or additional rollover protection a good 3-point retractable (i.e. standard shoulder belts) is the best and safest option... and Morris Classic just happens to make a very nice set of bolt in 3-points for 68-72 A-body cars.
