Some years ago when I was restoring my MK II carrier, I had the same problem with the pins. I had a few NOS pins checked for hardness and they came up at 54-56Rc. The original pins are induction hardened to prevent warping ( oven or flame hardening would produce banana like pins unless they were held in a fixture ) while leaving the center portion tough. The pins are cold headed to shape the end, the same process as making bolts. From the factory, the track sections were cold headed on both ends, with a joining pin with the cotter pin hole to assemble the sections. I have used .4375 dia. Class 60 shafting cut to length and then welded on the heads to replicate the original pins. One last point, T16 pins are slightly shorter than the pins used on UC track, Canadian track anyway.
