88 Tranny Question(s) ........

I Have An 88 Tranny Out Of A Civic Hatch Dx I Was Told The 88's Were Different In That The Input Splines Were 21 Count, And All Other Years Are 20,like 90-91 Years. Will The Tranny Work With A A.c.t 90 Civic Clutch And Pressure Plate???are They An Odd Year Or Something?? Please Help
Thanks In Advance
