What is the bolt pattern and offset for a 1961 Chrysler Newport?

The 1961 Chrysler Newport used a 5 x 4.5 inch (5 x 114.3 mm) bolt pattern. The offset varied depending on the wheel size and option selected. There isn't a single definitive offset for all 1961 Newport wheels. You'll need to consult a parts catalog specific to your car (based on its trim level and options) or a restoration specialist to determine the correct offset for your particular vehicle. A factory service manual could also provide this information.
