I know it's always nice to get a definitive answer from someone who has done something...but an alternative to that would be to cross reference the part on sites like LMC Trucks or others that actually sell the parts...

On this page you can see the 85 is the same as 85-88 meaning they will interchange without any other hardware. These are after market but the implication is in the part year range.
So if you find an 85-88 Ranger with a black steering wheel...chances are it will fit your column without any modifications or adaptors needed.
Or you could just order an after market one if you see one you like...make sure to get any adaptors recommended just to reduce the amount of running around or waiting for more parts to complete a project...
I hope that helps@!
EDIT: If it helps...you don't typically need a wheel puller right away if you pull the whole steering column from the connetion in the engine bay right to the wheel. This way you can score any trim parts, ignition, wipers and other items that might come in handy...then when you get the puller you can just take the wheel off...it is a bit more involved...and does require removing part of the dash...and there are three bolts on the floor holding it to the firewall...8mm I think...
And aside from that...I don't think Ford made a black wheel for those years...I know they had them in the 89-92 models but that was because the dash trim changed and was usually black...but those years do not direct swap...changes behind the dash are needed to actually swap in a later model column...and you need the dash also...so much more involved.
