I need to set up a rig for my college kid to use as a daily driver and want to swap 3.73s in for the 4.11s that I have now. Set up with 350 SBC, 4 speed, 33" tires, but just need to get top speed up a little to make this more usable. I'm having a hard time sourcing parts - seems like a few of the guys that were selling these (front and back) are not to be found. I already know/understand the downside of swapping out the 4.11s but for my purposes I have determined that it is the way to go. Any direction on where to source 3.73s would be much appreciated.
