Help needed to find a nice wheel combo, 72 swinger

thanks for your answers so far.
i checked which axle i have, it's the 7.25 stock axle (see pic)

to make it easier to compare which axle is mounted on the car i found a nice explanation pic



So if i got a 7.25 axle, it's for sure i have SBP?

Here's a pic of the actual, sry, awful wheel
