Right, changed them today, I just wanted to ask.

When you guys did yours, were there any visible differences between each mount?

My old mounts were identical to one-another. The new mounts had slight differences between them.

Is this because they were perhaps manufactured at different times, by different manufacturers, or for some other reason? The part numbers are also different.

Just wondered in case I put them on the wrong sides. The differences were one of the new ones had a flat base, the other new one had splines, and one had slightly more rubber around the circumference than the other. None of these differences appears to affect the way the mounts are fixed in place, or how they operate. They just appear cosmetic.
