Need Carb Help

hey , Hows Everyone Doing? I Opened Up The Hood Today And The Carb Was Leaking Gas. Its A 230 Flat Six With A Single Stromberg On It. Im Having Trouble Finding A Rebuild Kit For It......any Suggestions. Also How Much Do The Carb Shops Charge To Rebuild Carbs(if Thats A Better Way To Go)?
Thanks Alot

 

i Forgot To Add That I Am Having Trouble Finding Out What Model It Is . It Is Off Of My 1951 Dodge Coronet , And Like I Said Its A Flat 6

 

Do you have a manual transmission or a gyro-matic? By manual I mean is it a column shift?
