I currently have some 4.7 tcase gears w/ 23 spline output shaft and I want to install them. I was originally going to do dual cases with the 23 spline adapter but I have since changed my plans. I want to stick with a single case.

What is my best option for using the 23 spline output shaft? I have 22re with the w56. I was thinking about picking up a turbo trans (r151) but I havent seen any for sale locally in months and I am afraid that the price will be like $1500 for a rebuilt one from a toy only yard. Should i swap shafts and just stick with 21 or is the 23 worth the extra time and money

What size tire do you plan to run? Depends on how hard youll be abusing it.

But the cheapest way to make them work in your setup is with a 21 spline input gear. (spline count in this situation is for input, not output. )

Currently at 35s, plan to run 37s one day, wont go any bigger since i'm only on built toy axles. Dont wheel too hard but plan to hit hard trails and want to be overbuilt so I dont have to worry much about breakage.
