Is my motor mount the factory original? '91 LX AT

[wtfisafleek]

I'm looking to replace my motor mounts as it appears they've seen better days. The driver's side already showed up and I went to mount it, but it appears the left side hole is not big enough to accommodate the stud that goes through it due to the shoulder on the stud.

For the mount already on my car, the hole on the left is a little larger to accomodate this shoulder, whereas the replacement's holes are identical size. Was the mount on my car possibly modified to fit incorrectly, or is it possible the new mount I got is incorrectly made?

The new part in question is MRC part #A6512.

That mount in question is notorious for not fitting correctly.

I'll post some more info in a few when I get a chance.

Ok now that I'm at an actual computer with a keyboard.

The forward stud hole is too small and has to be drilled out to approximately 1/2" for the stud to fit. Nothing is wrong, per se, it's just that mount comes from the factory WRONG.

I got stuck in other areas, so I circled back to this earlier. The biggest drill bit I have is 1/2", and that slides through the aftermarket mount just fine. I'm willing to bet a 9/16 or 5/8 bit would be perfect. I'm going to take out the mount anyway, so I'll just mic it and see what I need.

Has anyone else reported any failures of aftermarket mounts that have been drilled out to fit correctly? The sticker on the box says "Made in CN", which I'm going to assume is China.

CN is another way or saying China.

The actual size needed is .56", so yes 9/16" would be perfect.
Not sure about failures though.

Oh, well nevermind, thanks for the measurement Jon.
