Well...they should be attached close behind the driver, from level with the top of the shoulders to 4" below that, according to the rule book.
The only place you have is the floor - if you find a set long enough. And that is not a good place. It could actually do more harm than good in certain situations. I think I would do without before I went to the floor.
I would ask some slow stocker guys what they are doing. Not a lot of options.
If the results don't match the theory, change the theory.

Remember, shoulder belts stop your upper torso from going forward only, the seat belts stop you from going forward and up. So I would set them angling back or to the back seat belt holes. Pretty much in same line as with a cross bar behind seat.

There’s no good way to do this, other than installing a bar-loop in just behind the seat. If you’re going to do that, might as well put a bar in. Any existing point in the car that you pick is going to be just as much or more of a hazard than a safety improvement. Just use the lap & anti-submarine belts until the car has a bar.

A roll bar isn't a bad idea even if it isn't required by the rules. Stuff goes wrong all the time, sometimes the guy in the next lane has a problem and he ends up in your lane. Even when it isn't your fault it is nice to have a little extra protection.

You're only going 80. But in Stock, you can have guys in the other lane going over 160, on 9" tires, and on the brakes.
Just saying.
A little different than the street class at the local track.

Get a rule book, you’ll find out you don’t need any of that stuff. Lap belt and maybe a helmet Got the rule book, got the helmet. It's just one of those "I'd rather have it & not need it than need it & not have it" things.

A little different than the street class at the local track. THIS/\ I asked a chassis guy about putting a crossbar behind the seat in a 14 second car to use 5 point belts. His answer was "Why you want belts in the car that will keep you straight up if you go upside down with no bar?".
"Everybody funny, now you funny too."

Remember, shoulder belts stop your upper torso from going forward only, the seat belts stop you from going forward and up. So I would set them angling back or to the back seat belt holes. Pretty much in same line as with a cross bar behind seat. Since we are NOT referring to highly reclined single open wheel seating, it has to be noted, any seat strap has to be restrained at each end to be effective. Most comments here are focusing on only one end of the shoulder belt, the downside of improper positioning is spine compression, not good. But what I see overlooked, the other end of the shoulder belt attaches to the hopefully across the hips, lap belt. When the upper torso in an accident moves forward, and applies tension to shoulder harness, the end attached to the lap belt pulls the belt up into the stomach area. A lap belt across the hips is properly containing the largest bone structure in the body. A lap belt that crosses the lower stomach area is in one of the most vulnerable/softest parts of the human body. The misnamed 5th "submarine belt" in our upright seating sedan cars is what prevents the shoulder harness from pulling up the lap belt into the kidneys,liver, pancreas, bladder, etc. in an accident. Your gonads are of minor concern here. Positioning well the 5th belt is nearly as important as the shoulder belt mounts.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

aftermarket belts need to be changed every 2 years per nhra most all track enforce that , oem belts even from the 60's do not expire (even 60 years old) gary we buy these belts because they supposedly are SAFER than OEM belts, yet 50-60 year old belts are ok, never mind the possibility of them being "stored" out beside the shed for the last 10 years or so. if they are so good at that age, why even bother to install aftermarket belts that need to conform to xyz specs ? just head out to the local junkyard and grab whatever belts you can find. they will be FINE ! and as to the "slower" cars not needing aftermarket belt replacement every two years, not around here. you put those belts in, they need replaced, period ! unless, of course, you run at an outlaw track where almost anything goes. the excuse given for the two year replacement rule is "we don't know what condition the belt is in." well open your eyes and look ! frayed stitching or webbing, hacks or cuts, improper mounting ? good cause for rejection. yet dried out, stiff webbing, frayed stitching, rusty hardware factory belts still ok ? yeah, RIGHT !
