Anyone using 16" Split-spoke Mustang wheels on their car?

I'm looking for a cheap set of alum. wheels for my '73 Dart and I've found a set of 16" splitspoke Mustang wheels for sale locally.

I've found they have a 5.27" backspacing and are 7" wide.
Anyone know how these wheels would fit in relation to the balljoint?
Spacers needed to get the tire away from the balljoint?
