which trigger plate to use

[ajpm26]

So I've been putting my 2g together and am stuck on a few things.

I have a 1g 7 bolt with evo9 pistons I'm putting in my 2g currently.
For timing, Which crank trigger plate should I use? I have the 2g one off my old 7 bolt and I have a 1g one. Also, I'm using a 1g cas, so it wouldnt matter if I had to use the 1g plate since there's no more crank sensor.

Also, how do I know if I put it on backwards or not?

Thanks
