The Moki 2.1 comes standard as a beam mount (like your .46) but you can buy a special backplate that allows you to bolt it to your firewall (like your motor mount on the .46).

No biggie, works either way.

If you are talking about on-board ignition, there are many on the market. I use the JHM model with great results. Full instructions on installation come with it.
