The spec for the holes on Centric part number 122.66024 is .53 dia. The ones I received had .63 dia. which made them a 122.66040 for 71-72s like you say.
For Sale Info added on 2/3/13:
The drums with the .63 diameter holes are for sale here - - - > http://67-72chevytrucks.com/vboard/s...d.php?t=561651
