Need Help With Spacers

[Dirtyray]

I have C5 Corvette wheels and am trying to put them on my 1980 malibu. Does anyone know how much wheel spacers I might need? Has anyone else done this? Front wheel is 17x8.5 and the rear wheel is 18x9.5

What is the back spacing on the wheels You have?

 

[Dirtyray]

I am not 100% on this but I think the back spacing is 7.6"

It needs to be around 3.5" to 4" I have a 8" wheel on the back of mine it has 3.5" back space. I don't know if a 9.5" will fit without mods to the wheel tubs or frame. unless it sticks out of the 1/4 .
