Assuming this is a 68-72 A-body axle, you need adjustable aftermarket control arms with metal ball joints. The A-body axles have the control arm attach points in a different location and at a different angle than the G-body cars. Simply forcing the axle in place with the stock arms will bind the suspension. Also, be aware that the A-body axle is a couple of inches wider, so you'll eventually need rear wheels with different offset.
Also note that A-body 12 bolt axles are about worth their weight in gold to restorers. You may want to consider selling the 12 bolt and getting a correctly-configured 9 inch housing. You might actually come out ahead financially.
