a friend of mine has a set of original 5x4 Torque Thrust D's magnesium centers, with tires, he told me $1100 for the set about a month ago. Someone painted the centers white, but said he would remove it if i, or the buyer wanted.
Saw those last summer at the Seattle Mopar show in Everett. I considered buying them but decided for $1100 he needed to keep them. Pretty hard to find but they are out there, just have to look.
Try MOTECH. They have some wheels that have the correct offset you'll need for an A body
