Spare Tire---82 GMC Short Bed

[ryap]

When I purchased my 82 GMC pickup shortbed it had the tire mounted in the bed. I was told the reason it was mounted there was becuase at one point someone added a hitch. From what I understand back in the day when they did that they had to pull out the spare tire carrier, which forces people to mount the spare somewhere else. First, I want to know if that is true and second what do I need to do to put the spare tire back underneath while still having a proper hitch. If anyone has any insight it would be very helpful.
