1200 Brake upgrade - Calipers??

[_smp_]

so, I'm about to kick off a front brake upgrade to my 1200 coupe and am going for the 280zx rear rotors and Sentra/ Sunny calipers combo.

I won't be needing vented discs and would rather not stuff around with maching hubs/ sourcing drum hubs, so have decided to not go down the S13 route.

so, I think I have found some calipers...although am not 100% on them.
looking for some advice to see if I have found the right ones...unfortunately I cannot see them in person so am dealing with a dude via email. My gut feel says the model on the right...whaddya think?!

any advice appreciated!

and yup....thinking of starting a build thread soonish...

Doing that conversion at the moment they look to be the same calipers as mine i use g20 s cargo ones same as sunny/ pulsar
