68 Chevelle back spacing help please

[Windy City Chevelle]

I have a 68 Chevelle SS no mini tubs wilwood disk brakes and calipers all around. I'm about to order forgeline wheels and I measured but since I've never done it before can anyone help with back and rear spacing. I want to run front 18x8 (245/40/18) and rear 18x10 (295/36/18). I believe front spacing would be 4.5 and rear 5.5. Can you guys please help I need to know my tomorrow thanks a lot

Those backspacing sizes look pretty standard. What you need to make sure of is the pad height for brake clearance. I'm sure Forgeline can definitely help with that.

4.5 b.s on front sounds right for an 8' rim.5 3/4 to 6" on the rear.brake changes can move your wheels in or out so check with wilwood if the brake kit moves it in or out from stock.with my c5vette swap the rear wheels got moved out 1/8 each side,in 1/4" each side on the fronts.measure!!phil

I called wilwood and they said I changed the rear end to a 9" of notched the frame it would move the placement but if not then it doesn't. But it does move the front .18 of an Inch outward. So would my 4.5 back spacing for the front change And should I go with a 5.5 in the rear
