Replacement compressor dipstick?

[beamrider]

I have a CH 7hp 60 gallon vertical compressor, model VT627504AJ, and I notice I'm now in need of a replacement dipstick for it. Parts diagram isn't showing a separate part number for the dipstick, tho. Is this a generic "one size fits all" type of part, or am I missing something?

And while I'm at it, might as well change the oil, anyone have any recommendations on decent oil?

Anyone? I checked out a few similar models at lowes tonight, and that dipstick isn't there anymore, it's a screw on cap, and a bullseye window is set into the side of the pump.
