Hey Darren,
They are 15" X 7". The front will most definatley have to go up, no room to turn. I was merely checking front clearance since I had lengthened the wheel wells by 2.5". Raising the front will intern make the back look lower or at least more level. If you go to my 2fine69s page you'll get an idea of what it will look like, since I have already put this combination of wheels on the car before I tore it down. The front will probably be lower with the V-8, but I now have 892/893 torsion bars in place of the six cylinder ones. The rear will also be lower once I put interior, bumpers etc. on the car.
