It does not fit as the rb6 had a much narrower chassis and is longer.

I am currently running 78/22 on my Orion 8.5/r10 pro combo. It was slow and way undergeared do I added some boost and +3 degrees on the endbell and it is rocket fast and came of at 99 degrees after a six minute main.

They are using Kimbrough gears for an Associated. You will need the slipper pads as well. Most locals here are running the 72 spur with a 32 pinion in stock blinky 17.5
