Do I need a new distributor body?

[JimZ]

Can someone tell me what the dimension should be between the opposing contacts inside a good distributor body. Mine are measuring 2.372” and 2.382”. I am surprised at the .010” difference and since my rotor to contact distance varies from .033 to .038 depending on which contact the rotor is lined up with I am wondering if new bodies have a tighter tolerance between contacts. Thanks.
