Rear Diff Insulator for EARLY 240Z. I believe they were the same up until 06/71.

Need to call in the order in shortly.

Thanks in advance.

55415-E4100 or E4101 or E4102 or N4301 is the last update in the fiche.

Now get back to work! (me too...)

Thanks Jim. Both numbers come up in a search at courtesy but the price is $15.00 different.

Both show available.

According to this site:

55476-E4101 is the proper number up to 6/71 but to be sure, click on the number for more info to double check! I don't want you to get the wrong one haha.

Hey, you! Get back to work! :ogre:

Thanks Jim and Decoy. I ended up ordering 54145-E4102 for $36.00. According to the link decoy provided (which I will bookmark at work) N4301 supersedes the E4102 but both are still available. I'm a little confused but the dealer (nissanofchesapeake.com) confirmed the latter is correct for my car. I guess I will find out Tuesday.

Thanks again.

FWIW - My 7/71 car still has the early, forward located differential. So it should use the early style mount. When I replaced mine several years ago, I used 55415-E4102. Fit fine.

... According to the link decoy provided (which I will bookmark at work)...

Glad you found the link useful, for me it's a gold mine when ordering parts from nissan

Thanks again. Part Number 55415-E4102 was an exact replacement to my failed insulator.

Have you bought one of the Ron Tyler mounts? If not, it is good insurance to keep the new mount from failing.

I have thought about that for the next Z but I am keeping this one as close to stock as possible.

I have thought about that for the next Z but I am keeping this one as close to stock as possible.

I can certainly appreciate the desire to keep it stock, but since the R-T mount is 100% reversible, I saw no reason not to install one in mine. The improvement in the driveline lash (and therefore around town drivability) was great, and well worth it. I kept my stock strap, and could revert to stock in under an hour.
