Are these holes for seatbelts?

[Shipp]

I bought a middle seatbelt for my 71 F100. I was planning to double-mount it on the bolts for the other seatbelts, but I see there's two holes nearby that look like they're potentially intended for this. I've attached two photos. Is that what they're for? It doesn't look like there's any threading, so I suppose I'd have to put a bolt on the other side...? Seems to me that isn't how you'd attach a seatbelt.

Thats all I did on my trucks is attach the new belt to where the originals bolted. Works great.

I may do that yet, but I haven't been able to get the bolts loose.

Spray from underneith with PB blaster and I would DBL up on exsisting bolt---seems how it threads into a welded nut under the cab

yes the bolt is suppose to carry the extra set of botls. those botls are a pain to get loose. don't forget to pick up that penny.

A good spray down of wd-40 or PB and an impact will take em right out. And yes you can double stack them
