I bought new 3 point seat belts from Amazon for a fraction of the price that the popular supply houses charge. Choice of colours was good. The only issue was that the webbing from buckle to floor attachment part was too short so I made an extension with 3/8" aircraft style cable.
I used a kit from Julianos that fit very well and was easy to install. I have never wished I did not have those seat belts. I got the 3 point in burgundy and they kind of match the seat upholstery. https://www.julianos.com/product-p/jupb3nr.htm
I put a set in from my parts '92 F150 into my 1949 3600, I knew the whole history on the parts truck and it's low miles. The retractor sits neatly on the floor. I also had to use extenders as the 49 seat seems to sit higher or at a different angle from the F150. I made my own backing plates including the long one that you feed in from the top for the shoulder points. Had the boy start the lower bolts from the top and I went underneath to hold 'em in place
For some reason I don't have one of it with the seat installed, probably because I'm DRIVING it But you get you the idea.

On mine (Juliano's kit), the upper attachment is backed by a plate with a welded nut. The recommended procedure was to tack weld (or tie) a piece of coat hanger to it to help get it into position. Once the bolt was started, I wiggled the coat hanger enough to break the tackweld and got the coat hangar back out.
The access behind there is tight and at a little bit of an angle so I don't think that something non rigid like a string will help much. It doesn't just hang down. You sort of have to push it at an angle. But using the string as a safety might not be a bad idea.
If you have a wife or kid available with a small arm and hands, they might be able to reach down in there and hold it in place.
