Bruiseruptor rear axle for Bruiser build?

[amstel78]

I apologize if this question has been asked and answered, but my Google-fu failed me today.

I'd like to run 1.9 scale wheels on my Bruiser build. I was planning on purchasing the RC4WD 12mm hex adaptors to use on the front Bruiser axle, but the rear in order to keep the track width the same as front, was planning on running a Bruiseruptor rear axle instead:

Yota 1.9 Straight Axle (Bruiseruptor Edition)

My question is this - do I need to order the Yoyta axle shock mounts like RC4WD is suggesting: Yota Axle Shock Mounts (x4)

Or will this axle bolt right up using the factory Tamiya parts?

The RC4WD axles have a different gear ratio (2.67:1) so if you buy a rear, you need to buy a matching front. Also, the spring spacing on the front axle is slightly different than the original Bruiser so I'm assuming its the same for the front of the re-re. The front RC4WD yota axles spring spacing is the same as the Tamiya Hilift which is a few millimeters wider. Some have used them on the Bruiser but I don't know if they widened their front or not. I have added spacers that i made from scrap aluminum to mine for the proper width.
