Default Body mounts question

I asked this in "What have you done to your D21 today' thread and figured it may just be better to have a thread for this answer.

It might also be a really dumb question but I've owned only unibody cars and no body on frame trucks or cars. I found out from being underneath that I am missing the bolts in my rear cab mounts, 95 King Cab V6, and the FSM has nothing that I found with information in regards to them and installing the bolts. I'm guessing they have never been there in the year I've owned it and who knows how long before I came around. However, now knowing this information I would really feel a lot more comfortable fix this issue and knowing that I am not in a cab held on by the front mounts only.

I've pulled the jumper seats and don't see any access to it. Is there no access inside the cab? Can I take a small holesaw and make access? Is there a threaded portion on the cab mount and just a bolt goes up from the bottom of the frame mount and threads in? Or is it a thru bolt and nut? Does the cab need to be pulled off to do this or can it be done sitting on some jack stands and finagling it in? what size is the bolt that's needed?

Anyone that has their projects going on right now and have their cabs off or have had their cabs off that can provide insight and/or even better, pictures, would be greatly appreciated.

Hi Shady.i just discovered the exact same problem in my 1987 D21 kingcab.
Been making banging noises since i got it about a year ago.When i go over hard camber corners it really thumps.Well i was just turning the corner to my mechanics garage when extra loud BANG reminded me to tell him....He takes for drive "no banging here??? Oh there it is!"and after some poking around he showed me the cab was loose at the back.
Mount bolts missing.Now i have to wait until we can find some replacements from a wrecker so it can pass it's Warrant of Fitness.I'm a bit pissed,someone left the bolts out.All this time i been trying to figure what the damn noise was.Told mechanic i thought the torsion bar was either broken or the bushes worn?Well at least i know now.

Tne nuts are "captive" attached to the cab, you thread the bolts in from the bottom as was said.

Whomever needs bolts to fix this issue, I have the exact bolts needed to replace missing bolts.
I used to have to tighten mine up every 6 months due to the popping action action when loose.

Another problem with the rear king cab mounts is they tend to "collapse" slightly, you can see this when you look at the body line between the cab and the bed, the cab usually will be sitting slightly lower. As far as I know this only effects the king cabs.

I will remove the rear body mount bolt, jack up under the body slightly and insert a large flat washer between the mount and the cab floor, than lower the jack, reinsert the bolt and see if the washer you used was thick enough to align the cab and the bed.
