STS-PI and PI 3A+

Will the supplied cut-outs only work with the 3B format boards or can I use a 3A+ board? I want to minimize power requirements so that powerbank will last longer.
Thanx

The holes for the bolts are in the exact same position on the Pi 2, 3 and 4 boards, so it should fit.

It worked perfectly for the 3A+.
Thanx
