There are some photos on fold3.com (free access), showing some groups of cluster bombs on P-47s, but they seem to have fins, not the parachute. Links are to the photos, the next page to the right typically has an explanation. One of the photos seems to show a under-wing mount, the others seem to be on the belly.
