Hey guys i am looking at a 51 chieftain,, the body is really clean,, im asking if anyone has gotten into floor pan repair or replacement. The foor in front of the rear seat and the left and right front corners are rotted away . The rest of the car is all original with straight 8 , car is absolutely complete. Its a 2 k investment, i would just like to know if anyone has done a floor in one. Thanks and God bless
