  • Price
    $1 - $2,000
  • Location Australia
  • Condition Used
Description:

I'm looking for a Series 3 RX7 Diff, I'm located in Australia so would need a seller willing to help with appropriate packing. I think Pack-n-Send can pick up and send internationally.

I have a S2, 81 RX7. I want to swap it to a S3 diff with the stronger 26 spline axles, and the 114.3 PCD so I can redrill to 5 stud.

Thanks

I believe I have in my storage a pair of axles and third member with a LDS upgrade.

It needs a bearing charge.
