Center bore on a Mopar 4.5 bolt spacing

I need to cofirm the bore on a 4.5 bolt spacing for my Cuda. The wheels are going to be drilled to order. If measure roughly 3.18 on the bore. Can this be confirmed? I need to be 100%, so I know what I can expect in the future. Once their cut I own them. Thanks Bill.

Most mopars used 2 13/16 or 2.8125 wheel hub
Check your measurements again and have the machinist go slightly larger suggest at least 2.82

Magnums are not hub centric rims. Just the lug nuts hold them center. Thats why good used set that don't have the lug holes all mushroomed out are hard to find.
Sometimes old magnums get bad and they lose there torque.

They're always 2.813. 2.820 makes for a nice slip fit, go much tighter and you'll start to have problems. I've run 0.004 clearance on rims before and they'll pull a vacuum as you take them off. In fact, if you pull the rim off the hub a little ways, the vacuum will pull it back on. Makes the guys at the tire store freak out!
