oil filter mount pin

Long story short, the oil filter was seized to the mount so we had to pull the whole thing off. I got the filter off of the mount, but a pin fell out of the tube , my question is does the pin just drop down that tube with the point down?

Got a picture?

There is a roll pin that sticks into the block to prevent the adapter from rotating when you bolt it up. Check out the pics at http://www.madxj.com/MADXJ/technical/technicalfiles/ARoilFilterConversion/OilFilterConversion.htm.
