Fork/triple clamp interchangeability 81/80 YZ

Does anyone know if the triple clamps and forks of an 81 YZ250 (43mm forks) will bolt up to an '80 YZ250? I want to replace the stock forks (38mm) and triple clamps with those off an '81. Wondering if the triple clamps were the same size and would bolt right up? Also wondered if the dual pull front brake hub will fit in my '80 hub? I read somewhere that they weren't interchangeable. Thanks.

That's what I was hoping. I just scored the forks, triple clamps, and front wheel/brake assembly for 100 bucks. Forks just had new seals put it in. Thanks for the reply.
