Does anyone have a TCI chassis in the 47-54 model. I was wondering because i recently had ordered and put mine together and now it is coming down to picking out wheels for it. I know the width i want is about 10.5" wide by 20" rims in the back. I have extended rear fenders in the back so i can fit wider tires and give it that street rod look. So i guess my question is " What backspace and offset would i need for my wheels?" From the front of the rotor on the rear to the frame is about 5 3/4". I have never really had to order wheels without a set of originals in front of me before
