Another 10" wheel question!

[6camaro9]

I am wanting to run 10" wheels on the back of my 69 camaro and was wondering if anybody could give me some back space numbers and tire sizes. Also do I need to consider getting my rear end norrowed any. I know I have seen this on here before but I can not find it anywhere. Thanks for any help.

Stock rear, run a 5.75" BS with a 275/40/18. Its a tight fit. Some 69's will need some tweaking here and there to help with rubbing at an aggressive ride height.
