Should Rear Engine Mount be Offset? - 3000GT/Stealth International Message Center

I was looking at rear mount this evening, (thinking about going poly), and noticed the bolt sleeve is not centered . . . Is that normal?

Photo attached.

that seems to be the same with a buddy of mine that we switched out two weeks ago. i guess it's ok?

I have a pile of mounts in the garage. I can take a look tomorrow.

I pulled the mount out today and noticed that the rubber has a crack in it above the steel sleeve. . . . Now I am REALLY wondering if mine has sunk a little.

Anybody have dimensions of where the sleeve should be, relative to the center of the mount?

Mine is offset like that. It, too, was ripped. I replaced it with a solid mount.

The photos in that link, as well as others I found today, all appear to show the bolt sleeve to be in the center of the rubber.

Does anyone have a relatively new OEM, or a solid mount that could be measured from the base, up to the center of the bolt sleeve?

i think it's, at least partly, due to the angle you're looking at it from. you're kinda looking "up" at it. so it's a little bit of an optical illusion.

I just installed solids, I believe my rear mount was undamaged. I'm at work right now but when I'm home I can measure it. PM me if I don't do it tonight because that means I forgot

Maybe it is suppose to be centered.

Its rubber though, add heat, weight, and torsional forces from the engine twisting around in the engine bay and 10-15 years of service and I would guess it won't be in the center anymore and its probably leaning towards the area where weight and gravity will take it.
