I bought some direct from http://www.redlineoil.com/ just weeks ago.  About 8 bucks/quart, took 4 days to arrive.  It's been highly rated on list in the past and I'm happy with it.  Used the same MTL in front too.

  Subject: lube

  I state for the third time does anyone know of any manufacture of GL-4 gear lube I can't find any.  Someone said Castol but they didn't know for sure.  My manual says GL-4 for the front diff. too.  You guys said GL-5 was ok for the front diff. who is right?  
      I TRY TO USE THE ARCHIVES BUT everything I search for is not found what is the key?
