frame rail(s) for 67 barracuda

Rusted out UCA area on left frame rail too sketchy for repair, so looking for drivers and maybe passengers side frame rails for my 67 notchback. I am not sure of which years work but I believe 63 to 72 are the same...chime in if you please! why oh why aren't these repro'd....thanks for looking. Can pick up at Carlisle
