Excellent sources! Already placed in my newly established go to file. I have used spot weld drill bits on another project and with care they will release the majority of spot welds w/o to much if any collateral damage. So I will stick with them as suggested.
Note, the FULL replacement aftermarket panel sweeps past the visor mount location. In the compound radius area of the cab corner. Should give me an advantage of not requiring to much if any exotic sheet metal forming techniques.
