Do I have enough clearance for tires?

I got 245x15s on my 72 with a 4 1/2 backspace wheel (15x8). I had to take the channel locks to the fenderwell for peace of mind. An easy inch to the springs, 1/2-3/4 to the fenderwell. It didn't have enough rake to it, so I cheated and added Hi-Jackers with about 40 lbs. That really opened things up.
