1949 plymouth restore

I was hoping to find some one to talk to about switching the master cylinder on my '49 to an upgrade or just the best way to go about restoring it and any other tips would be appreciated!!!

Hemmings News lists many part suppliers for your car, just finished a resto on 59 Dodge and 55 Chrysler in my shop. Upgrade meaning dual master? The are many specialized websites based on your year car, google them and have fun!

Thanks alot!!
