Retracting Seat Belts

[ChallengerHK]

Do the retracting seat belts use the same mounts as the lap-and-shoulder belts?

I saw a product previewed on a car show recently that claims to fit the OE mounts for the front, may be able to use for the rear as well but they do not claim those to be ready made.

Thanks for the info, Wade. I was asking about the stock retractables from the 74 model year. I've got a set, and I'm trying to find out if they bolt into my 73 mounts or if I need to do some mods.

I've read that the '74 shoulder strap come out of the rear panels & you have to cut an opening.

It does at the bottom, yes. I'd love to be able to claim some foresight, but the truth is that by sheer luck I've held on to those as well

Forgot to continue. What I'm really looking for is "Do they use the same hardpoints?"
