Mounting Triplanar Tonearm to SME 20/2 Turntable


I just got a Triplanar U2 SE tonearm and am wondering how to mount it to my 20/2.  
The arm board I have is for an SME tonearm.  Until now I've had a SME IV mk vi mounted.  
After removing the SME arm I used the TP jig to see approximate location of the three holes.
Two of the holes land on the aluminum of the board and the third one is in the open hole in the center.  
It does not seem likely that I will be able to use the SME arm board for the TP arm.  Unless using only two holes to mount it will be enough???
I've also wondered about using 3M high bond tape to fix the arm to the board.  I use this tape in my profession and find it to be of excellent strength and longevity.  This doesn't mean that it's an acceptable application.  Just curious.    
In searching these forums and internet searches I have not been able to find a TP compatible arm board for use on an SME TT.  
Please share any info you might have.  Thanks!

Why not just drill the hole where you need it??

But yes, tape will be just fine. Possibly maybe even better. In fact the main drawbacks to tape are its a little harder to tweak into position, and then also to remove, depending on how permanent the bond.

My Origin Live Conqueror mounts sitting on an aftermarket jig that makes VTA adjustment easier and more precise. This includes a layer of teflon between the arm and base. It allows the arm to float. Tried it both ways, its better like this. In other words this like everything else you can never assume but just have to try it and see. Only way to know for sure.

In this case you could for example try fastening the arm with the two screws, then try with tape, then if two screws are better go back and add the third. Or not. There is no right or wrong- as long as the arm doesn't go flying off and crashing to the floor!
@millercarbon I can drill two holes and might just do that.  The third hole is not possible since it's in open space.  
I could also have a wooden disk cut to the same size circle as the SME arm board and attach the TP arm to it.  I don't want to detract from the aesthetics of the system, but I suppose I can paint it  black so it blends OK.  
One other thing is I live in St. Paul, which is where Tri-Planar HQ is located.  I've contacted Tri-Mai and he said he can help me set it up.  I would still like to hear other ideas on how to best convert this before I meet with him.  Thanks for your help!
Dear @snackeyp : First than all contact directly to SME asking for advise(help I think they will help you:

enquiries@sme.co.uk   or  +44(0) 1903 814321

In the other side you can do it only with those two holes or with the 3M tape but you don’t lost nothing to contact to the manufacturer of your TT.

Regards and enjoy the MUSIC NOT DISTORTIONS,
