I have got myself into a little problem so I am looking for help with some measurements. I am trying to calculate wheel backspacing measurements but my truck is currently in pieces. I would like to know the measurement from the outside on the frame rail to the interior of the fender wall and the exterior of the fender wall for the front and back wheels. To my knowledge, it should be the same for "48 to "50. I can use these measurements relating to my aftermarket front and rear suspensions to calculate my backspacing and order my wheels which will allow me to roll this beast around.

Any help would be much appreciated.

 

Did you get the stuff I sent and if so were they any help?
