18 spline abody box?

were they even made? im thinking of going with an 833 and having it faceplated by liberty for the future, and id like to go with an 18 spline if i can find one for the right price and condition...were 18 splines ever made in abody tailshaft lengths? is there a way to convert a 23 spline to 18 spline? id rather not put in a b/e body 18 spline if i dont have too...id just like to know this stuff so i can keep my eyes opened for it!

thanks!
