500 RWHP... What's the best setup without the need to shim too much or shave anything down. I also have the Wilwood big brake kit that needs to fit... I'm going up to 31 spline as the stock rear bearings are SHOT and I figure replace it all while it's apart. Any ideas on what fits the best? The shop recommended the 35 spine Strange axle C clip eliminator with a $1,200 diff... I think that's overkill... Is there anyone out there that has installed a 31 spline kit with minimal issues and great results?
