The first thing to consider is the pin arrangement.
They are, for the most part, different between manufactures(however that can be overcome by rewiring and soldering).

The next thing is the frequency has to match exactly for optimum performance and if it off quite a bit, any performance.

It doesn't look particularly promising.
From what I can find, the Tesoro coil spec is: TX = 950 microHenry, 4.3 Ohms; RX = 15.8 mH, 63 Ohms
Whereas the F75 spec. I measured as: TX = 690 microHenry, 1.9 Ohms; RX = 6.95 mH, 37 Ohms.
So you've got too much inductance on the TX, which is not good - if it was too little, you could do something about it. The resistance is too high as well, in my opinion. The RX side is perhaps acceptable.

I am almost inspired to try building a clean sweep type coil for a Tesoro.
It's in the back of my mind.......... a few other projects need to be finished first.
