Weld wheel backspacing for Dart front wheels

So... :scratch: .... that would be close to a 15 x 5 with 3 1/4 backspace right. :scratch: That would be the same outer spacing, but an inch deeper on the back of the wheel, right?

I just wanted to make sure the wheel wasn't going to tuck to far in or hang out of the wheel opening area if I went with a 3 1/4 on a 5 inch wheel.

:scratch: Anyone have a 5 inch factory wheel they could measure just to be safe!

THANKS IN ADVANCE
