[Overdriven]

I know what it's like to on an allowance too. I've personally clearanced RPM arms for the driveshafts with a sanding drum on a dremel before with no issues. Rpm makes a set with the required dimple, but I had to clearance mine further for the extra high ride height I was running. I'd run it with the 2.5 knuckles and axle shafts, go for a motor first before new knuckles. The only thing I'm worried about is how much material was removed from the axleshafts to fit the 3.3 shafts. But I'd only be worried when they break. Good work, lack of $ is the best inspiration IMO.
