Need help finding oil for my rearend...

[Marck]

Hey guys..

Being from Denmark I often run into problems with getting parts locally, but everytime Google saves the day.. But I've been googling like a mad man, with no luck..
I have a Strange Dana 60 rearend, and want to change the oil in it... Strange recommends using 75w-140 non-synthetic from any well known brand..
Where can I buy such an oil?
I can find synthetic types everywhere, but I'm assuming they recommend non-synthetic for a reason...?

Thanks..

I think they recommend non synthetic for the clutch packs.  Any 80-90 weight gear oil should do the trick.

Here in the US "finding oil for my rearend" can mean many things.

Haha, it kind of means the same in Danish, I just wasn't thinking along those lines when I wrote my post.. 
Just to clarify, for Bull's sake, I'm talking about my Charger...

I'm a complete oil newbie, so bare with me here..
You're saving that any 80-90 weight non-synthetic should be fine?
I've read the same from other internetpages, but I hesitate when Strange recommend otherwise..
Why would they then recommend an 75w-140? 
I spent a lot of money on the rearend, and would like to give it the best possible conditions..

I'd use any good name 85w-140 non-synthetic which should be real common.

I use Spirax A axle oil  high quality heavy duty  LS90 made by Shell. It's a non synthetic oil. To that I add Additive Friction Modifier by Motorcraft.
