Looks right to me. They're straight 'roll' pins to prevent the main pin(s) from working their way out.
I have the same type of pins on my ballast box... my only implement that required a knobed-bushing. The bugger of that was that there are two different spacing holes and, of course, one of them was in the wrong hole. I was easily able to knock the 'roll' pin out using a centre punch, re-position the bushing and re-use the pin.
Mind you, I'd keep a couple of spares in the shop... just in case you ever need one.
