that's bolt pattern

tire rack has 8 wheels listed with offsets around 12mm, one is 8mm but the other 7 is either 11 or 12. and yes, the bolt pattern is 5x4.75in or 5x120mm

3.5-4" backspacing works well depending on tire size and rim width. What size wheels and tires are you planning to use? Most of the newer age rim styles wont work on G-body cars but there are still a lot of wheels to choose from. Centerline will custom machine any offset you want but they are on the pricey side depending on style.
