[Farmall] Farmall 450 LP, Hydra touch filler plug

[Harry Clark]

Can anyone tell me the measurement from the filler plug, to the full mark on the 
hydra touch dip stick?  I have a '58 Farmall 450 LP and the dip stick is broken 
off at the plug.  It is a recent purchase and I don't know how full to keep the 
reservoir.  I am having some hydraulic problems and want to make sure I have an 
adequate amount of fluid.

Thanks, 
Harry Clark
