Engine Engine mounts location

[Manic Mechanic]

I need some pictures of stock AMC 258 i6 / 4.2l inline 6 engine mounts and there location. (Both sides) Both frame mounts and engine mounts.

The issue is the motor is sitting to far forward (about fist width off the firewall) so I need to see what holes in the frame a factory setup is (mine has 6 holes in the frame and is currently in the forward 4 most) and the engine side in case they got swapped left to right in the past at some point.

Otherwise everything is factory including T-5 Transmission Dana 300 and drive shafts etc

Mine are not stock, Mine came with the 4 cylinder, but I do have a AMC 258 i6 / 4.2l with the MORE engine mounts. So I don’t know if that would be helpful.

Dose it sit correctly? If so why not

The MORE mounts will use the same location.

It doesn’t squat like an hippo in the Luangwa River.

It's not squatting but it is sitting to far forward. Far enough in fact that last time I went off road my front pinion hit the oil pan

Driver side. 1st looking down from top

Driver side from floor looking up. 1st is front, then middle, then back side looking a little forward

Passenger side. First looking down from top.

Thank you. I will compare them to mine in the morning. I really do appreciate it.

Here’s photos of my motor mounts, 99% sure this is stock 86 CJ7 with AMC 258 i6 / 4.2l and T-5 tranny.
Tape measure is from approximately center of large hole in frame right behind shock mount. Still has plastic valve cover and gives about 1” clearance to fire wall at base of valve cover (2” at top of valve cover).
Bolt pattern of motor mounts is different between driver and passenger side. Photos aren’t labeled but you can identify by differential housing.
Let me know if you need further photos.

From what I can see driver's side your in the front set of holes and passenger side your in the front and back set.

Here's mine I wonder if the frame mounts were switched (left to right) at some point. I merely put them back where they were when I installed the new motor. And yes the old AMC 258 i6 / 4.2l sat the same way.

You may be right about mounts being switched side to side. Is there a bolt hole lined up for the missing 4th bolt on each side?
The passenger side mount is about 4 1/2” long where it meets the frame on top with a long relief dimple on top rear. Driver side mount is only about 3” long on top where it meets the frame. If they are the right mounts and on the right side they should both mount with 4 bolts. Front 4 holes on drivers side and 4 outside holes on passenger side ( with center holes empty).
I’ve included pictures on inside of frame mount also if it might help.
Also, in order for your motor to move rearward, your Transmission & Transfer Case will also need to move equally, so I’ve included pictures of my Transmission support/ belly pan for reference. Mine is an 86 T-5 so if different year or tranny that location might be different.
Didn’t take a picture but my valve cover to firewall is only about 2 fingers clearance with the plastic valve cover which is rounded on top back ( not as square as aluminum).

I will have to look tomorrow. But I don't think my ps is that wide TBH. I will also have to look at my skid plate.

These are the only pictures I have at the moment of it
