pics of rear 18x10" wheels with backspacing of 5" and 5.5"

[WHITE AND RED 69]

I am going to order new wheels next month and I am trying to find the right backspacing for the rear. From other posts I have seen some people have either 5" of 5.5" of backspace. So far I am leaning more towards 0 offset (5.5") but I want to see the options I have before I order. Does anyone have any pics of 18x10s on their car with either of these backspaces. I want to get this right the first time so I am looking for working combos without any tubbing or relocation of leaf springs. Thanks

I´m planning also buy 10" wide rear wheels and with that "wheelguide" 5.5" backspace seems to be ok!

Thanks for the website. It looks like having a 6" backspace would center the wheel better in the wheel well. Does anyone have any photos of 5.5" or 6" backspace?
