Agreed. Lap belts would at least keep your head from going through the windshield (and as stated will keep you in the car where you are safer than outside the car). I've had problems finding the right size belts for my shoulder harness and have thus removed them and only use lap belts in my 70s Lincolns (shoulder belt is not adjustable). I will probably check with one of the links provided in this thread to see if someone will custom make the lengths I need for a reasonable price. To date, I had only found places willing to make what I need in batches of 100 and I only need 2.
