RMCHRGR you are correct on the welding and specs for the cage.. my rule book is up to date.. keep in mind that most suppliers of these cages are selling the nearest thickness over the spec(.118) that being--.134 so as long as you know what you are buying the thickness should not be a problem.. i bought mine from art Morrison for my 63 Dart..was a good pre-bent setup thats only needed to be notched after it was cut to length..
