Where on the rear subframe do these two unique bolts go?

I pulled the subframe off over a year ago and stored all of the "rear end" bolts together in a box. I've now finished sandblasting and POR15 painting the rear sub, all of the links and the spindles and am re-assembling with poly bushings. (It looks great and should handle fantastic)

While sorting through the bolts I came accross these two that are unique and I can't remember where they go. The one is unique because it has a washer that none of the others have, the other is unique because it has the rounded head where all the others are flat with the stamp.

I've looked all through the manual but it's not specific enough in reagards to bolt length or thread. Can anyone help me out here? I'm hoping that some one else has had this problem or that someone who will be under their rear end this week could have a look. I have to believe that the Nissan engineers made these two bolts different for a specific reason and I want to put them back in the right place.

Thanks

Jeff

Thanks n240sxfnatic

That's not it, I have the aduster bolts in the correct locations on the subframem see pic.



What baffles me is that there is only one of each of these, I's expect to find two of them if they went through the bushings or held on a control arm. I'm beginning to wonder if they are from the rear transmission mount or some single part other than the suspension that is held on in the back of the vehicle. They are rather large bolts so whatever they hold on must be big.

Have you looked at a FSM to look what it could be?

Yep, tried the FSM. I have the softcover from Nissan but it isn't detailed enough, it lists the torque required but it doesn't specify length, thread, hardness or physical description of the bolt used.

About the only way I can think of figuring this out is to look or have someone else look under their car and locate it by physical appearance.
