Where to get Pins for A-Body Pin Style Calipers

I have a set of pin style calipers from a 73 Dart that I am going to use with a set of Cordoba 11.75 caliper brackets for my 72 Dart. Who sells the pins for the calipers? Are the B/E body pins the same length? Are the calipers the same as the B/E body calipers?

Any help will be appreciated!

Thanks,
Joe
