[Roadsters] question regarding correct wheel offset for datsun roadster

[Mtbdavid2 at aol.com]

Hi,
  What is the correct wheel offset for a Datsun Roadster?  Will  wheel size 
14x6 with bolt pattern 4x114.3 and O offset work or is the  offset 
incorrect?  If the offset is incorrect is there a way to make it  work with 
185/60/14 tires?
 
Thanks,
David
