L6 motor mount question

[LowGT]

I'm replacing my dying 250 with a well maintained low mileage 250. I'm doing a few maintenance items while I'm in there, one of them being all the dried out/cracked motor mounts.

So I ordered them from Rock Auto and the front mounts look nothing like the originals. From what I've searched here the mount style may have changed due to safety reasons, but I haven't found any clarification on what it looks like. So can anyone verify that I have the correct mounts?

What was on the truck looks like the one on the left. The new ones I just got look like the one on the right. So are these the right mounts? I can just bolt them in and run them with the original perches?

Thanks for the help!
