Dave when i did my 69 dart i split the wheel wells on the seam and welded in a 4 inch piece of sheet metal widening the wheel wells to fit a bigger tire. when you opened the trunk it still looked stock.
That sounds good but I think the B-body wells are pretty big. my tire borders to the east and west are basically the adjoining pinchweld lip where the quarter meets the outer wheel house and the other border is the leaf spring.
I can go 10x15 with.... 5.5" backspacing I think? and... (I'm winging it here but this will be close) 295/50 R15 tire?
It fills it, gives like 3/4" to 1/2" of clearance on fender lip side and leaf spring side.
