fitting IS the hard part.if you can get the header with the rubber upper's that bolt to the rad surport,makes the header a little easyer to fit.i just changed the 70 header to a 73 header[hit a deer].its heavyer then 70-72 headers.the valance was not that bad.i used 77 t/a fenders also.but now i have 7 70-73 fenders to chose from.they have the right brkts for the valance.heres a pic after i replaced the bent parts.it looks crappy now.
