wheel experts please

i will make this simple. i need a set of 16" steel wheels for my 93" grand am for the winter months. I have custom wheels for the nice weather, but unfortunitly our summer doesn't last long. Anyway, the stock wheels are aluminum and 3 out of 4 leak! Apparently they pretty much self destruct after so many years. I have 4 good 16" tires though. I tried to order 16" steel wheels at the local junk yard and i guess they weren't available for an early 90s grand am. only 14" and 15"

So my question is this:

What other car has the same wheel dimensions as my 93 grand am gt, 5 spoke aluminum wheel?

16x6bolt pattern is 5-100mmoffset ????? how do you measure (special tool)?
