Show me your frame connectors

If you have a welder and a chop saw. I would buy 1.5 x 3 steel tube and make them. About $40.00 in metal and you do not have to cut the floor. You will also need 2 - 3 x 5 pieces of plate steel for the ends. I have done one set on a 68 Dart and will be putting a set in a 64 Dart in the near future.

If you want to cut and weld them into the floor use 2 x 3 steel tube, this is my 2 cents.
