I am having trouble finding the right carb kit for my chrysler. I have a '79 140 charger serial# 1409h8a. The numbers on the carbs are TC1A and 440061. Thats the only ifo I have. I just need to know what carb kit to buy. When the system is pressured the carbs drip. Everyone I call says they dont know what kit I need. Can anyone help??
