What wheels Aluminum Slots or Mag 500's

Well, any opinions are welcome, I'm trying to decide what to do for wheels.
My car is a '74 Dart Swinger, I put some 15" turbine wheels I have for a different car on it for now, but I think the wheels don't look quite right on the front, either too wide a wheel, or not the right backspacing. It is hard to tell in these pics, but the wheels seems to stick out slightly wider than the fender, not much, but enough to make it look funny.

Current tire size is 15x7.5 235/60/15 in front, 275/60/15 in rear.

Anyway, so I have a couple sets of used ones I found to go look at, figured I would ask for peoples opinions on what would look better...

Magnum 500 15"x7, would I be able to get 275's on a 7" wheel?

Aluminum slots not sure the width yet, but the current tires are F60-15 and G30-15... does anyone have a good pic of a swinger with slots?


and on a different subject, I need to screw around with my pics, how do I get them larger, but stay under the required size? I must need to screw with the pixel/inch ratio rather than just resizing them...

Thanks,
Matt
