Patrick's might have the license for reproducing the Wayne items. As I posted above, Patrick's has had problems with inventory control - they might also have a problem with cashflow for pre-payment of a production run of the licensed parts (this statement is simply speculation). This delay in delivery has also taken place over the past 15 years with respect the the 3.55 R&P set.
Does Patrick's have your money? If not, have you checked with another vendor? Patrick's provide these licensed parts to other vendors. Maybe you can find one that has inventory?
Try Chevs of the 40s?
