47-55.1 3 point or 4 point seat belts in 52?

[NeoJuice]

I purchased lap belts a while ago and I was going to install them in the truck until the 'wifey' said no way.

So from a safety point of view I'm looking for either a 3 point or 4 point harness to use in my truck with original bench seat. Using the 3 point I would need to drill a hole for the shoulder belt. If I used the 4 point I could run the belt over the bar and bolt it to the floor. The only thing I worry about with the 4 point is not having the adjustability slack needed for shoulder checking as you would with a 3 point.

Anyone have any thoughts? Or should I just go get some shoulder belts out of a vehicle at the wreckers? i tried to use the search feature on the page but didnt come up with any results for 47-54 and what people might be using.

At some point down the road the bench seat will be reupholstered.
