When I bought my 1973 240z, the PO said the differential came out of a 510. It is a 3.90. Not sure if he was positive though. Does ayone recognize the mystery diff? It is slightly lighter weight than the stock diff. The pics with two diffs have the stock(so he told me) diff on the left and the mystery diff on the right. The individual pic is the mystery diff. Thanks, Victor.

Looks like I didn't install the pics correctly. May need help on this.

You need to host those pics on the web somewhere, including your personal album here, and then put the IMG tags around the URL where they are located.

510s have R160s. They are lighter than R180s and use the same halfshafts and everything. I see no reason why the PO didn't tell you the truth.

No, he doesn't HAVE to do that. He CAN do it that way, but it can be done much easier.

They can be attached directly from his computer directly into his post.

From the "reply to thread" page where he creates his post, scroll down to where it says "manage attachments, click there, and follow the prompts to select what you want attached., click "upload photos", Bam! He's done.

Thanks for the pic help.
