Seat fasteners to body

[90BlackMJ]

Good morning! Would somebody pleaseeee snap a picture of what the seat mounting fastener nuts look like? 
 

bucket seats, I don’t think it matters tho. 
 

in my mind they are probably a 13mm with a big flange washer. Can’t seem to find where I put em

I could get a photo if you need it, but yes, it's a 13mm flange nut.

Thanks! I know weird question. But I want my restoration to be proper.

The ones on my 90 have a captured washer that’s a bit larger than the one in the pic

Do you know if yours are original? Mine is also a 1990, and I have a bench seat. One of the bolts was replaced with a hole at some point so that one has a bolt going down into it instead, but I have no reason to believe the other ones aren't original.

My 90 that I purchased new has flanged nuts exactly like the picture above, as do the 88 and 89.
