There are two operation lists here (with repeats between the two lists) with contain the co-ordinates for many drop zones.

There are a series of "Dick" drop zones but none labeled specifically "Dick 8". Since in many cases the pilot is also listed with the date, maybe you can still match things up to identify the drop zone. While most of these drops are USAAF, there are some listed that are not.
