I got a 93' strait six long bed 4x4 with dual tanks and supposedly towing package. i was wondering how to find out what rear end i have and what gearing? maybe one of u know what was offered on this truck? Also i would like to know what suspension lift ya'll recommend.....also tires and is there anything i can do to make my gibson exhaust louder? lol sorry for all the questions but i was just curious.
