Abe,
Nice score! Sweet plow truck! Now you can plow the whole road in and charge your neighbors to pay for the truck?!?!?

Did it come with chains? Is it a Meyer Plow? Which engine is in it? It did come with a trans cooler from the factory but I’d confirm if still attached.
I don’t know your knowledge on plowing but you want to put the ballast behind the wheel wells in the bed of the truck. A good rule of thumb for ballast is to find out the weight of the plow and use the same weight for ballast.
Just like underwear you can get 4 uses out of the wear edge. Like it is now. Turn it around. Turn it upside down. Turn it around again.
I’ve got a Power Bleeder w/ multiple master cylinder attachments that you can borrow if you need it? Easiest way I’ve found to bleed brakes. Especially when doing it alone.
