Maybe?, depending on the housing width. I had the same, springs in the frame, stock 67 b-body rear and 10" wheels. Mine had 6" backspace and about 3/4 clearance. I had 29.5 slicks so the front edge of the wheel well moved foward about 2". (Big hammer)
My Duster now will have 15x10x 5" backspace rims with stock spring position, a-body width housing. Front part has been reworked also.
Might add those 4-1/2 wheels puts the tire very close to outside wheel lip if down at stock height.
