Correct gear oil weight for 70 Dart rear end

[Al Bundy]

Hi,
What is the correct gear oil type and weight for a 1970 Dodge Swinger with slant six/auto trans with stock rear end? Also how far below the fill hole should the oil be?

Thanks

With your warm climate, 80-90 would work fine. fill to the bottom of the fill hole. If you overfill just let it drain till it stops.

Fill on level ground.

It takes right at 1.25 quarts.
And of course the bottles are 1

Good old 90 weight is just right.
