My transmission died in my 90, and I got my hands on a 23 spline from a 91. I know I have to pull the input shaft on my 231 transfer case and swap it for a 23 spline version.
Looking at novak-adapt, it seems that before '90 they use a "short" 1.2" shaft and post '90 they used a "medium" length input shaft that is 1.7".

That being said, should I be ordering the "medium" length shaft for the post 90 transmission, or should I get the shorty version of the 23 spline shaft?
I know its likely safer to get the short, but thinking about spline engagement strength it would make sense to go with the longer "medium" version if that is what normally would be there.
Thanks for the help.
