Default 4:11 rear

My 69 Corvette currently has a 3:73 rear. I would like to upgrade to 4:11 ring and pinion. Can someone please direct me to the best place to purchase a gear set? Any help would be appreciated.

Most transmission shops can install the gears for you if you cannot.

Your going to have to buy a carrier also. It might be cheaper to just buy a complete unit or go to 3.90.

You can run 411 or eve 433 gears on your 3 series case. Toms sells them and they may be some of few left he has. I think I have a new set of 411's as well.
Getting the job done can be accomblished in many ways by many people. I suggest you decide what you want and how you want it done as not all jobs are the same in either price or quality. A little research may be your best option at this point.
