70 duster seat belt question

I just installed a new set of seat belts in my 70 Duster. I was told that they are correct for my application, but someone has told me that they are not. I am having problems with the retractable lap belts that go between the bench seat and doors. They are tight and cause the doors to be hard to close and rub the door panels. Can you guys tell me if these are the correct belts for my 70 Duster?

Thanks,

Jason
