They are cragar Ss 15x7 for the fronts and 15x10 out back. I know the fronts will fit but what do i need to be able to fit them on the back so they don't stick out to far.Measurement wise.

 

Get your reciept and return them...lol. There is not really any way to keep them from sticking out so far. That has to do with the offset of the wheel itself. Depending on the type of wheel, they may sell different offsets depending on the application.

 

tons and tons and tons of vaseline. hehehe im kidding.

There is a tool you can rent or buy that will measure the backspacing you need. You can do that, and then bring back the 15x10's and get the correct back spacing. you might have to do a little mini tubbing or at least a little lip work.

 

Lip work = 20lb sledge and some good aim.

 

I am glad I haven't bought them yet. There is 4 1/4" backspacing, 3 3/4" backspacing, 3 3/4" reversed backspacing, thats all I can find right now for rear backspacing and what do they mean reversed backspacing.
