And if so what kind of backspace do I need? A friend has some cheap Torq Trust II on a 5x5" PCD and running new 235/40 & 245/40 rubber. I reckon they'd look awesome on my '66 LeSabre if they will go on without hitting anything. Other than driving 2 hours to pick the wheels up to try them as my Buick is laid up for the winter and a little resto work, anyone any thoughts on what backspace I'd need to get those wiiiiiiiide rims under my fenders. I did hear a guy had 8x15 and 10x15 under a '65 or '66 Wildcat and had 245 on the front so a 9.5x17 low profile with a 235 shouldn't be too out of order? Any help is great guys.
