As said, it was an available over the counter tranny.  VSE and TA Specialties used them a lot.

I replaced the broken T-10 in my '77 with one (now called a Richmond 5 speed).  I've been very happy with it. 

The Doug Nash 4+1 was specifically designed to replace automatics and make use of their numerically lower rear gear ratios to improve performance and fuel efficiency.  My '77 had a 3.23 which was almost too steep for the 3.27 1st gear of the 5-speed.  I swapped in a set of 2.73's & the car drives just like stock, but with the 2.73, I run 2,500 rpm at 70 instead of 3,100, which bumped hwy mileage from 15 to over 18.  Doesn't sound like much, but it's over a 20% improvement which makes a huge difference at $4.00/gallon.

To answer your question directly, no 5-speed transmission was ever available from the factory in any 2nd gen...
