[Roadsters] Trying to source crank main bearings

[BARTERDUDE at aol.com]

Trying to keep my numbers matching G motor for one of the Single Carb 1500  
running.  I have an option on a crank that has been turned .20 under on the 
 main bearings and has sat for years and is somewhat rusted, so the shop 
thinks  we may have to turn it another .10 under.  
 
Anyone have any sources for Crank Main Bearings that are .30 under for the  
1500 (understand the 1600 three main is the same too)?
 
Any help on sources would greatly be appreciated.
