BB A body pitman arm

YO, this is cawley. I am in need of a good pitman arm for my 69 barracuda big block. All the ones I have came across are wrong for my car. My pitman arm where the splines are, where it goes on the steering box measures 1 inch. All the ones I came across are 1 1/4. So if you have one & you are going to Carlisle please let me know. I will be there Thursday to Sunday morning. Thanks
