273 Damper/Harmonic Balancer Differences?

[Bossanova5]

Hello all,
I have (2) 273's.
One 66 273 two-barrel Single pully belt (no P/S or A/C) damper which has two balancing holes drilled in it.
One 66 273 Commando Double pulley belt (With P/S) has four balancing holes drilled in it.
Can I interchange the dampers between the two engines?
Thanks

Both are neutral balanced engines so they should interchange.

Yes they are both neutral balanced. One just needed more weight taken out to balance it. All 273 and 318's are neutral balanced as are 340's from 68-72.
