Engine ID # help

I have 2 95 trackers that were manufactured about 6 months apart. My problem is that they both look different. The older one I know is the original because of how long I have had it but the other was bought a few months ago. Both engines are 1.6l 16 valve and I have tried to find the # on both cars but have not seen it. Does anyone possible have a picture of the location so I can get a better idea? I have tried the manuals and have not found one informative enough and I need to verify that the younger tracker has the right engine.

Thanks in advance for the help!
