Replacing Front Engine Mount

[Seadweller]

I'm going to be replacing the front engine mount on my '98, and bought the "new and improved" version. I understand there are two rubber isolators called "Engine Mount Support Stops," but given that I have the newest engine mount, I'm not sure which part number to use for the support stops. I've read where they didn't fit in some situations, and I can only assume there's more than one version. Which version do I need to fit the newer style engine mount?

Thanks!

Don't remember the part numbers but you need the 987 mount and side rubbers.
