I grew up with these old trucks. My dad and granddad were former dealers, and my first ride home from the hospital was in a '52 L-110 [no, I don't remember it]. So I have a soft spot in my heart [and maybe my head] for these old trucks.
The mechanical stuff was simple and straightforward. If your truck has the floor-mounted emergency brake lever, you'll notice the handle resembles the lever system IH used on their manure spreaders, more than the more "automotive" type used on the K-series.
A set of brass drifts and some hooked pry bars will help a lot in dealing with these old trucks:

They made their own bolts simply because it was more cost effective for them than buying bolts from a supplier. At one point, when our garage was dealing with an outfit known as Parts Associates [PAI] out of Cleveland, my dad showed their sales rep where he could buy his bolts from IH at RETAIL cheaper than he could buy [supposedly] wholesale from PAI. [Old IH parts people will remember "CT" pricing on certain items, and most bolts carried CT prices.]
While you're in there, I'd recommend replacing the race. Better to do it ONCE and button it up, than to just replace the bearing cone and then have to go back into it again when it's less convenient.
