Shock Absorber Guru's

I am still plodding away on restoring my 79 KTM 250MC and need some input from the experts regarding some questions I have about the rear shocks on this bike. It has a pair of Marzocchi's with the integral nitrogen cannister. On the underside of each cannister where the schrader valve is located there is a decal that says VG-4 65. I am guessing this is the style and or model. They are sort of a off gold color with black and red springs. They appear to be in really good shape but neither have a nitrogen charge and one seems to have minimum to no dampening.  How much and what kind of oil should these shocks take? And how much of a nitrogen recharge should they get? There is a small screw at  the top of the shock body. Is this where you replenish the oil?  All advice and input is greatly appreciated.

Hi all,
I've got a pair of 13" Marzocchi piggybacks that I'm going to rebuild. What kind of oil should I use for them ?? Will ATF work or should I stick with some 2.5 or 5 weight fork oil. Any help would be appreciated. Thanks !!
