Paul mand Doug, that's exactly the issue I'm trying to avoid. I almost ordered new belts until I re-installed my old ones and recognized the problem. Actually, I first noticed that they were too long retracted. The driver's side (shown in the pics above) has a little shorter length of belt when retracted. I think 133" is too long for these belts. I didn't mount my upper loop as high on the b-pillar as sone do, because I wanted to keep the belt behind the door when retracted.
As far as I can tell virtually all new vehicles have a free-sliding latch. Both my trucks, and both of our Infinitis have them. I wonder why these seatbelt companies don't make that standard on their seatbelts. If I can't get a free-sliding one I'm going to just buy a set of belts and disassemble them and replace the latch as long as it works in the buckle. I've searched and can't find a charcoal sliding latch, but both my trucks have that color. Then you have to put some kind of button or stopper on the belt to keep the latch from falling to the ground, but at least it will stow right.
Here's the button I'm talking about....
