Also, what rating of lube should I use - GL-4 or GL-5?

GL-4

So what about the Mobil 1 gear oil? Would anyone recommend running that since it is just about all I can find locally?

Make sure it isn't GL-5 I had a hard time finding a GL-4 I got the Redline I ordered it thru the mail and it came quick and easy. It was a racing website I believe if you are interested I'll try to find the info.

SYNTORQ is a 75w-85 oil maybe thats why it runs a little cooler?
