The wheel housings? Any way to just get a boneyard piece cut off of anything and cut an bend and weld and make it work?? Only way I can ever get close to such is taking flat sheet and just cutting and banging and bending and forming till it works and weld all the seams, crude yet it works....sorta. Really need 18 ga but that is hard to work and 20 ga. is aweful light! Bu I bet those dudes on TV car shows with their fancy trip hammers are banging 20 ga???
Years ago I did a 69 Coronet RT and had to get the outer wheelhouse from same yr 4 door car, it took some work but it worked out good.
