I have the HPA strut tower setup, since I started down the STU rabbit hole before the 1M came to market.

It's just sitting around doing nothing, I'm certainly open for offers.

One thing to note on that OEM choice, unless something changed between the 1m version and the M3 version for the piece that sits on top of the strut tower, those 3 nuts that go through that piece to mate to the studs are special. They have an extended sleave to get more threads to engage. I'm sure folks have figured that out, etc. or found it not to be an issue somewhere.

You can see the 6 sleeved nuts in the HPA pictures. It doesn't look like your parts list includes these 6 bolts (or they are included within the other parts? Usually oem parts don't do this...)
