Nut size for 2nd row bench seats 2018 Yukon

destman · Sep 18, 2024

I just did a swap on my 18 Yukon from captain's chairs 2nd row to bench seat. There were 8 big nuts that I was able to reuse. The passenger side seat seems to also have two studs on which the driver side bench is placed on and gets secured with two smaller nuts (one in front and one in back). I didn't have those on my captain's chairs - just had some rubber caps.

Does anyone know the size of those nuts or a part number? I attached a photo from the web of the nut in question between the seats.

MEH, Just find a nut that fits laying around the garage then go match a couple up at the hardware store, dealer is gonna want a left finger for one anyway......

I haven't been able to find a nut that matches around the garage. If nobody knows what the size is, I'll have to go buy a few from the hardware store and see what matches.

I'm pretty new to GMCs and I was really hoping to find a website with parts diagrams, part numbers, specs, etc. like they have for other brands but there doesn't seem to be a site out there with that level of detail.
