Number of Spokes on a 1981 CB750k

[Eltoncb750]

Hi Guys
I need some help, I have a 1981 CB750k Canadian model. I have sent her in for a café racer conversion, but now I need to source spokes as my old ones are a bit corroded.

here is what I know, the front and back wheels both need 40 spokes each, am I right?
also, they require 2 different lengths per wheel. I believe it is a 8x127 and 8x127.5 on the rear and 8x200 and 8x200.5 on the front wheel.

what I need is a confirmation of this? I don't want to order the parts and they are incorrect as these spokes are pretty expensive. photo attached

thanks Guys
