18 spline Hemi/440 A-833

A-833's are all the same just the spline is different and the O.D. of the front bearing retainers are different sizes. Check the hole in the trans vs the O.D. of the retainer.
Also the tailshafts are different lengths, A-body vs B-body.

In addition the 18 spline A-833 uses a larger diameter throwout bearing.
