Will these wheels work?

Yeah those might not work for a lowered car unless you cut that inner lip out maybe.

Yeah that would be my guess just by looking at it. Of course the angle of the picture and all of that make a difference in how it looks. A BBP 7.25 or 8.25 is ~56 3/4" drum to drum, the A-body 8 3/4 with BBP axles is ~57 13/16", so the difference is just over a 1/2" per side. By the math that makes it really close on the quarter side, but that picture looks like it's a bit beyond close. Which is a good reminder why everyone should measure their own car before laying out the cash for something.
