I got the Valvoline at a local place called Knechts.  I'm sure they don't have them where your at, but I've seen it at almost all the parts places. O' Reilly's, Schucks.

I put GM lube and posi additive from the Chevy dealer in my new rebuilt rear end. That's what Motive Gear recommended.

NO it's strictly rear end lube and be sure to get the additive if it's positive traction.

I know you already found your trans oil, but you can also still get CRC Sta-Lube 85W90 GL-4 at NAPA.

For the rear end, you can use a 80W90 GL-5 oil & the GM posi additive.
