TACH CONTROL UNIT FOR 66 FORMULA S CUDA

I am buying a formula s dash mounted tach, but it doesn't come with the electronic can. All Points said for a little extra $ they will provide their electronics in a custom enclosure, so I won't need the original can.
Here's the rub...
After reading this post I may have another issue. The 65 cuda I just bought doesn't have the stock points distributor. It has the GM internal coil electronic ignition upgrade. I'll have figure out what I have to do to make the formula s tach work with that distributor or go back to the Mopar ignition setup.
Any advice here?

Here's a pic of what I did on my 64 push button cuda. The tach is from at 64 GM. The console is from a 64 automatic polara, machined to accept the cup holder
