Transmission length 904 vs. 727 vs. 4-spd vs. 3-spd ??

There have been a number of driveshaft questions this week.
I hope it's a indication that everyone is getting their car "on the road"!!

Are the following statements both TRUE?

All A/B/C/E 904s are the same length "SHORT" & there are "SHORT" 3-spd & 4-spd manual transmissions for A-bodies.
** Is "SHORT" the same dimension? **
All A/B/C/E 727s are the same length "LONG" & there are "LONG" 3-spd & 4-spd manual transmissions for B/C/E-bodies.
** Is "LONG" the same dimension? **

Does this help?

That certainly answers my question, thanks!
