Hi, straight forward question here, which I don't know dah?, can someone please tell me how many bottles of diff fluid I need to buy to fill an 8 3/4 diff with sure grip in a 68 Cuda. Thank You

You need to purchase 3 bottles.
It takes around 2 1/2 to fill it.

Don’t forget some limited slip/sure grip additive/friction modifier if you have a sure grip rear! The Ford/Mopar stuff is good too

Mymopar.com has free factory service manual downloads.

It's all in there

Thank you very much 512Stroker, 66340SEDAN, Dana67Dart, I didn't want to over buy as the synthetic stuff is expensive and Keystone Automotive will not take returns on any chemical or fluids.
