Correct bolts for seat bottom latch?

70 Challenger

I figured out I’m missing the latch on my seat bottom.

Found latches for sale, but the kit doesn’t include the bolts.

Does anyone know the type bolts needed for this?

That is the catch for the latch.

Inside the seat back is the latch for the catch.

I will take photos of the latch to attach.

I’m actually missing everything, that was a reference photo.
So I need info for the catch bolts also.

Here’s my actual seat bottom.

Same bolts for the catch & the latch. (five bolts per bucket)

Bolts;

Thx for the pics,

So about 1” long, are they 1/4 or 5/6”

1/4" -20 & 7/8" from under the washer to the tip.

I may have spares, but I'd have to look.
