The cost to go from 30 spline to 33 spine was $35 so it seemed like a no brainer. I waffled over 1310 vs 1350 but figured bigger is better. I'll run a 3R/1350 conversion u-joint in the interim. At some point I'll have a driveshaft made that has 1350 on both ends.
He did mention I'll have to open up the holes on the stock drum backing plates to fit the axle bearings. Not too big of a deal. I've been researching 11" drum conversions. Might do that down the line too.
