Here is an example of the differences
The one on the left will work
The right one will give you the problem you are having
I have the brackets on the left. Time to see if it was just those rubber tabs on the mounts holding it up

FYI, I have a set of mounts I got from O'reillys (same p/n) & the China man who made them has the inner rubber angled so I couldn't get the bolt thru, trying two sets of G body block side mounts. I even left the mounts loose & still a no go. I ended up using my Energy Suspension mounts after the dumb blonde finally read the installation instructions.
Okay, I cut the rubber tabs off and with that was able to get the drivers side thru bolt in the mount.... Then the passenger side was way off. Same distance as before but opposite. It appears the distance from driver to passenger side motor mount holes is less than the distance between the motor mount bracket holes.
So I lifted the block out, again, removed the new motor mounts and placed them side by side with the old mounts. There is a major height difference between the holes of the old and new. Old holes are lower and much closer to the crossmember/frame, the newer about 5/16 higher. This would make sense and it accounts for the new mount holes being too close together once in the frame.
Lesson here (so far) is do NOT buy O'Reilly's brand "Power Torque" Part Number A2292, just as Pagrunt advises above.
I drove down the street to Auto Zone and picked these Duralast mounts up. Same part number 2292 less the "A" in O'reilly's sh*t brand. There is still a height difference between the holes, but they look much closer. And the old mount is worn down a bit explaining the discrepancy. I hope I'm not being too optimistic. Tomorrow will tell.

I really worried about them after reading about the trouble pagrunt had with his mounts. As you know they aren't much fun to deal with when the control arms are in place.
They are unreasonably inexpensive and I don't like buying or using stuff made in China but the quality appeared to be good to me.

At had this problem too, so I used a stepped drill bit and made the hole bigger.
Which hole(s)? My guess is on the two upper motor mount holes. That might work since the bottom cross member hole is already ovaled out. I'm going to see how these Duralast mounts do tonight before I resort to drilling
No I meant the cross holes. The one the big main mount bolt goes through. I did that and manipulated the rubber portion of the mount around with a screwdriver until the bolt went on through
