How is this part called and where can I find it?

[86stang.gt]

Hi -
New to this forum and posting for the very first time because I was not able to find anywhere how the part on the photo is called and where I may find it. I have posted the photos of the passenger and driver sides. I am missing the driver side. Looks to me this is just a spring keeping the door from rattling perhaps? The spring is still there but the pin and base are missing.
I have a 86 hatchback GT if it matters.
Thanks for your help!

It's a [Seat Belt Tension Adjuster].


There is a plug you can get to plug the hole:

Under normal circumstances, the adjuster is removed when swapping out to a newer set of seat belts with more modern inertia reels.

I have not seen the actual plunger being sold in some time. I just checked again to see if someone has them. I don't see them.

I'd recommend setting the seatbelt to stay fully retracted and installing a clip on the belt itself if you want the adjusting feature.

An alternative might be a junkyard, eBay, or the classifieds section here on Stangnet.

Thank you Noobz347. I’ve learned something new today .
I will do as you proposed. Look for junkyards or install a clip on the seatbelt itself. Thanks again.

They may be able to help you, I've used them years ago on older fords.
That striker looks to not be very healthy, does your door sag? That sometimes causes the damage to the plunger for the seat belt retractor.

Correct. I am in the process to replace those strikers even if I do not notice any problem with the doors (they are not completely flush with the rest of the body but other than that I have no problem). Thank you for the link.

I'll bet the area around the door latch is beat up, also check the metal around the striker, they can/will develop cracks in that area.
Check your hinge pins.

If you're going to replace the strikers, I would replace the hinge pins too. They are the reason the strikers are beat-up.

Yyyyep. karthief caught it.
