I am making sure my pistons are file fit...and the top ring is supposed to be .0017, and the second ring is supposed to be .0019

My feeler gauge doesnt have .0017 or .0019. So what I've been doing is using .0015 and .002 on top of eachother for the first ring, and .0015 and .004 for the second ring. Will this work?

Thanks.

And also, I installed the rings per FSM specs.
But supertech has installation instructions that show the rings in different locations. Will this be fine..or should I do it how supertech has it?
