On 1970 thru '72, What is the left and right side turn signal/parking light grills made of? Is it pot metal (white metal - is that the same?) I have a crack splitting through the bottom of one grill and noticed what crazy price it is to replace. Can I weld this part? I have a mig welder only right now. Could those low temperature rods, the ones that you can weld aluminum be used? I know part of the edge is chrome, I'll just find some creative painting
