This kit is designed to replace the ageing plastic bushings that make up the 1st gen RX-7 wiper assembly. It currently contains the mounts where the linkage mounts to the body under the front windshield and the larger round socket for the arm that attaches to the motor. I do plan to eventually add the smaller oval shaped socket and the mounts to the firewall. 

Please note there are three version of the socket so you can adjust for your printer's tolerance. I was able to get by with the .3 version, but it may be different for you based on printer material or environment. 

For the anti-vibration mount there are two versions one designed for an aluminum or steel core and one designed to be used without. For the core it can be purchased here. If that link goes bad you will need a M6 spacer with a 10mm outer diameter and a 6mm length.

Update: Added firewall bushings with aluminum core to the 3mf and files folder. To provide a better installation experience the firewall bushing is printed in two parts and then press fit together on install. This provides more material for the mounts.
