Seat belt connectors

[SouthernBelle]

I am looking around for one of these. I have gathered that I can not get these new so I will have to go to a junk yard to try and find one. Can anyone tell me by looking at these pictures below what all Ford vehicles might have this type of connector?

Also I have had my truck for about a week now. There is only one thing that I need to have done with the engine (adjust lifters) but a friend of mine is doing this for free pretty (just wants a 1L Dr. Pepper). I have having a issue with the front driver side door. If I leave the door unlocked it opens just fine but if I lock it I have a heck of a time getting it to open back up.

I have taken it to two different places and got two different opinions on what the issue is. One says the door latch needs to be replaced and the other says that the rod going from the inside handle (I think he said) to the latch has been stretched over time and I just needs to be bent back in a Z formation and greased. What do ya'll think? Should I just start with the cheapest thing and go from there?

Thanks for any input.

First seat belt I think will have to come from an Explorer because of the way it's made (referring to the bracket that bolts it down) and second I agree with the bent rod theory I replaced my exterior door handle and got the rod to the latch just slightly out of place and the door didn't want to open.
