Could you use one on an F-body?

Would a Grand National 8.5" 10 bolt rear work in an F-body? Anyone?!

No, it will not.

No it will not. Does it have a torque arm mount NO.
It's similiar to the older mustang set up with upper/lower control arms and even those guys have made a kit to adapt a torque arm like an f body has, to get rid of the upper control arms. They do this because the TA design works better. In case you were thinking of adapting upper control arms to your f body---bad idea.

Sure it will work after you spend thousands to chop it to the correct length, get the brake backing plates welded onto it, and get the mounts to bolt f-body suspension all fabricated for it. So basically its not worth it. Leave the GN rearend on the GN.

Do you have a GN or just the rear? If you have a GN why would you ever think to do this? And no.

If, by some chance it's a GNX rear end, it MIGHT work, as the GNXs did have a torque arm. Whether or not the GNX's torque arm mounts would be compatible with the f-bod's is another question....along with width, driveshaft yoke, LCA mounts, etc.

the grand national rear end doesnt use a torque arm. it has upper and lower control arms

Oh you mean this one, it's been dicussed before. Good luck finding one.

Or how about good luck getting someone to offer a cover like that with a matching TA to bolt in the f-bodies.

A similar aluminum cover would be difficult to make yes, but I wouldn't think that a steel cover similar in style to the GNX would be all that difficult to design or make. Just design it so that it puts the TA on the driver's side of the axle. Then make the mount similar to the 9" TA mounts. Then you have a bolt-on solution to the torque arm problem of a 8.5" 10-bolt. Now we just have to find someone with the fabricating and welding skills to try to make one.

The '87 GNX used a torque arm/ panhard suspension like on an F-body:

only problem is...your not gonna find a gnx in your local junkyard, hell its hard to find them anywhere other than showrooms nowdays

No ones looking for a GNX, it would be nice to have a cover like that so people could bolt a torque arm onto a stronger rear that doesn't have a torque arm mount. Seems like someone can send some specs to china to get some built for $5 a piece and sell them for $500 to the f-body owners on the never ending quest to mount up a $50 junkyard rear.

And if you READ the link I posted either here, or in the other duplicate thread of this one, you will see that this company rents the fixture to position all the brackets onto a bare rear housing. And you will also see actual pictures of the torque arm, and the real part is not as big as the one in the diagram above.

I've been looking at this scenario for over a year now.
The forward end of the GNX torque arm connects to a bolted-in subframe member added to the standard GNs'.
The custom truck air suspension market uses brackets that mount to the rearend cover bolts.The brackets,at this point,are only available as part of a kit.
