seatbelts are locking

So I got new seatbelts. I can pull them out a half inch then they stop and I have to let it go back a little bit before I can pull it out another half inch. What is this all about. are they broken, or can I fix them. thanks for the input. Neil.

so what do u mean by you got "new" seatbelts?
and did you get new seatbelts and the recievers?

what!? you mean you have seatbelts?

What? You really don't have seatbelts? I deliver pizzas with my truck, so I am on the road 30+ hours a week just for my job. thats why I have them. I got New Old Stock seatbelts from ebay. The whole set up except for the receptors. because mine are thrashed. I figured out the problem. I emailed the guy I bought them from. It was a safety thing. they only come out easly when installed in the upright position. So if I get in a roll over accident they don't come out easly. So they are fine I was freaking out about nothing. . . as usual. thanks for trying. Neil
