how oil in the differential?

[firstgear]

The 3rd member supplier told me to add it up to the fill hole level.....well, there is only one hole on the differential and it looks more like a drain hole than a fill hole.....it is on the bottom of the housing.....so do I just poor the 3 quarts of lube plus the 4 ozs of posi lube into the housing and put the 3rd member in and button it up????????

thoughts?

notice in the photo below that there is no fill opening up high.....there is a drain plug in the very bottom....

notice plug on the very bottom

this is a Ford 9" rear.....

No it will be to Full and chance wheel seals will Leak!! Probly more like 2 1/2 and 4 oz additive!! Look on front of differential about pinion high in the side for a plug with a 3/8 square in the center!!

no, it is my '60 C1 frame......the front and rear suspension pieces have been changed out to Jim Myers racing parts.....front will have rack and pinion steering, coil over shocks and disc brakes....rear will have 4 link rear with 3.55 posi, coil over shocks and disc brakes.......383 stroker motor and Classic Chevy 5 Speed TKO600 tranny......

here is a photo of it last week......powder painted.....just starting to hang some parts on now for good.....

It looks so different now that it is painted....wow, what a difference and nice to work on too....
