A-Body 8 3/4

If you bought it why the what's something like this worth. Could be as little as $350 to as much as $800. What's the center to center on the spring perches, should be 43" for an A body.

Hope you got a good deal on it.

As far as a 440 with a mild cam, yes that rear will handle it. Wheels are tougher to come by due to the 4" bolt circle
