Help needed to find a nice wheel combo, 72 swinger

Anything is possible but it is probable you have 5x4, small bolt pattern
Even with Kelsey Hayes disc brakes (factory option) it would be 5x4
72blunblu told you how to measure, I would just do that

(Also, I didn't realize you weren't stateside when I posted those wheels, I see now they may not be the best option)
