How/where to fill 37 gearbox?

[cajunfirehawk]

Just finished up my 36 to 37 gearbox swap and ready to fill my gearbox, assume one of the nuts shown in the attached pic is the fill location? Can I melt/heat up some cornhead grease and put it in a syringe to inject in to the fill hole?

Cant imagine its takes very much?


(in hindsight, filling the box prior to mounting in the frame would have been easier)
