Doug, 
 no, no hole is not a design improvement.
 Remove the old bush, drill the new one . You may have to do tinkering 
here. What you need to do is install the bushing in the housing  to drill 
then remove it to clean it  of any burrs. Reinstall it and soak in motor 
oil overnight so the bush can take in some oil. 
 Most folks will tell you the bushing is prelubed, but it ain't 
necessarily so. These things are generic and bought by our "suppliers" in 
bulk so the only thing you can be reasonably sure of is diminsions
 If you get crafty, you might be able to drill the bushing without first 
installing it and then removing it. Perfect alignment of the holes is not 
required as long as you can provide some decent access  for oil to get 
into the bushing.
Good Luck
