its the rear seat belt cover part thing lol

i dont even know what to call it. ive been googleing for like the past couple hours each day and i am having no luck finding it.

does anybody know where i can get this part or at the very least something to start from?

 

Try this link

SEAT BELTS/REAR. Fits: 2006 Hummer H3 SUV | Nalley Buick GMC Brunswick

 

Unfortunately you have to buy the whole belt assembly too. You can get it through Wayne Auto here on the site. They are very good. It will cost you about 40 bucks plus shipping

 

good find a0128. That's what I would do. A lot better than having to buy the whole assembly.

 

Junk yards probably rarely/never sell seat belt assm so that part would be a give away or a few bucks.
My first stop for non critical parts is a good old junk yard.
I'll bet its not 10 bucks for a set.
I got all leather heated seats,$800.
your part is a "peanut" !

 

Junk yards will only sell the whole seatbelt assembly with it. I just talked to wayne auto. Package deal.
