Hey folks, does anyone know thread size for bolts attaching rear seat back and bottom to frame? I could also could use size for nuts holding rear seat armrests to frame?

I did try the thread sizers and cant get them into the armrests, and for some reason I cant get them started into the seat back and bottom.

Truck has been apart for so long I lost my carfully labeled and bagged hardware. If someone knows I would be greatly appreciative, I am definitely trying to save a trip to the hardware store!

Thank you,

Brett

5/16 x3/4". Not sure about the armrests.

The ones into the back of the seat that go thru the tubular frame are 5/16 x 1 7/8. You might just take an armrest to the store with you and fit a nut to it….

great, thank you! do you know if it is 5-16 24 or 5/16 18? yes, bringing the armrests in may be what I have to do!
