Upgraded "unbreakable" 

Front Differential Mount for 87-91 Rx7

I kept breaking the front differential mount, so after some thought I figured I could make a design that would work better, be stiffer, yet still allow some flex.

 
These pictures are before final shaping
This shows the back plate with bushings.

I used polyurethane shock bushings for this prototype.

 

This is the backing plate by itself.

This is the part that bolts to the differential.

This is the part that bolts up to the subframe.
This is the mount put together without bolts.

View is from the side as you were looking at the mount from the drivers side.

This is a mock-up with some long bolts just stuck through there.
This is an edge view as if you were looking at the mount from the driveshaft.
This is the backside of the backing plate before final shaping.
This is an odd edge view.

Picture of all Hardware and mount completely disasembled.  

I have been running this mount for over 6 months under heavy abuse.  It has withstood all types of driving situations including all my trips down the drag strip, all kinds of wheel hop, all kinds of chirping 3rd gear.  

I will be removing the mount for inspection in a month or two and making a few improvements to the bushing material and subframe side mounting bracketry.


You really think I'm gonna put a link back?
