Slant 6- v8 centerlink

What is the difference between the slant 6 & v8 center link. I have a/6 in my '66. My crude measurements show Ihave close to 2" drop on the center link. It appears I have 6 inches of clearance between the oil pan & suspension but that doesn't mean anything.Does anyone have the measurements between the two? I tried to search but did not come up with any results. Could be operator error. It would be awesome if I did not need to purchase this piece .
