Redline Oil which one and where to buy ?

[Quattro8880@aol.com]

I want to change the manual transmission fluid and the rear diff fluid in my 
88 80q. I got the instructions from some of you on the list, and thank you. 
What I need to know now is should I use the MTL90 in the transmission and the 
MT90 in the rear diff ?  or should I be using the same product in both ?  
What are the quantities that I will require for each ?  Where is the best 
place to buy Redline ?

Thanks
