I have a 1971 Duster 340,looking for information into axle specifications,trying to find out what axle I have,also PCD,car is stock I have some drag lites that are 4 1/2 PCD which I brought for my ford 9inch,but I understand they fit A-body mopars but when I put the wheels on,they don't seem to fit quite right. cheers

Axle should be an 8 3/4" (no bolt on rear cover, has a removable diff) stud pattern will be 4" PCD, you will not find much choice of wheels available in that stud pattern.
