I've got a few things listed on eBay including 3.54 and 4.11 differentials, 240SX rear brake calipers and other bits. Do a search under my seller name, ezzzzzzz.

Hi EZZZ,

I saw your 4.11 diffs on Ebay. Are these a direct bolt in for 71 240Z? I noticed that they don't have the side flanges. How do those attach? Are they just unbolt from the stock diff and bolt onto the new one? Any other mods needed to make them work in the 240?

Any idea what those puppies weigh?

Thanks,

Marty

You've got it figured out!! Just unbolt your flanges from your stock diff and attach them to the new one. Since he's selling the R180s it is a direct bolt in using your mustache bar and half shafts. I can't tell you the weight though, I bought one of these last year...maybe the year before and shipping was included in the sales price ($115 as I recall so it was a really good deal...I bought a 3.9 ratio though...but the weight is the same). I can tell you that these are not all that large but they are heavy. I'm thinking like 80lbs maybe. ???

Remove your bolt retained side flanges and slide them right into this diff. It is identical to your diff. The weight is around 57-60 packaged. The original flanges were pulled for a CV conversion (doable but not a quick swap of parts).

Thanks for the info.
