Differential Capacity

[Stingray74CC]

I'm having the gripping and jerking in my differential. I've already ordered a couple bottles of additive for it, but I thought that I'd go ahead and replace the old oil in there at the same time. Does anyone have any idea of the capacity of the Differential in a 69 or how many quarts will cover it? It has 4.11 gears if that makes much of a difference. I've been looking into the Lucas Oil products and have heard very good things about them. I didn't want to short myself of the oil when I had the differential drained.

Thanks,
Anthony
