That's kind of where I am at, struggling to find an off the shelf wheel that works.

The XXR 530D mentioned above actually might work, there is a 35mm offset option but the low offset is 20mm instead of 24mm. Not sure 3/16" is anything to worry about though. And I like the XXR 575 in phantom black, too and it has a 35mm and 25mm option. Plus they all look to be about $200 each.

I am further complicating things for myself with the struggle to decide if I want a 275 up front which forces a new rear axle (if I want 4 wheels all the same) or keep the rear axle width I have and settle for a 245 front tire.

When I do my 5.7/T56 swap, I expect to at least re-gear my rear axle anyway. And since it is currently just an F-Body 8.25" I kind of planned to move up to an 8.75" at least. Buddy just finished a Dana swap on his BB Dart and it looks killer under there. Either way, going wider since I might already be upgrading the axle might not be the end of the world.

The 575 is a decent looking wheel. It would be nice to make the rear axle whatever length that enables the same size and offset wheel for the front and back. I don't even know if this is possible, but it would be nice to rotate tires since the fronts get worn so fast in autocross.
Man if I were having to swap rears completely, I would seriously think about going with an 8.8 Ford. They come with disc brakes already and you can usually find them with posi units in them if you get one from an explorer. I haven't done any research on the lengths, but I'm sure they would work even if you have to cut the tubes down to a length that would work, then get some axles made. I personally think Danas are too big for A-bodies. I think they create interference problems with exhaust and you won't be making enough HP to justify having such a large rear end. I know you have a budget mind like me and the thought of paying for a complete A-body 8-3/4 or Dana pains me.
