Wanted Mainshaft

Is 23 1/4 inch for an A body trans? Your ad really doesn't say.
I have a mainshaft, but I'm pretty sure its out of a B & E body A-833 trans.
Don't want to get it out of storage, as it's buried deep, if it's not what your looking for.

I believe so. My transmission guy said I needed one with those measurements. With also 40 spline 1 & 2 hub and 40 spline 3 & 4 hub.
