Interesting
definetely easier to find than GL-4 oil these days..
Last time I bought Sta-Lube I had to drive 45 minutes to a Napa that actually had it in stock. one that was half hour away that showed it in stock called me when I ordered online and said the website was wrong, they were out and weren't ordering any more.
If atf scares you use GM Syncromesh fluid...about a 50wt gear lube

  Did you decide on which way to go? How did your trip go if you went yet?  
   I and others are interested.
Just take note that GL5 does not play well with yellow metals like ssyncros... GL 4 is OK but I would still use atf.

Gear lube 7s designed to absorb shock loads that you don't see in constant mesh transmissions.
