Hi - i am looking for a set of the 1272 style 15 x 7 aluminum wheels with the 5 x 4.75 bolt pattern. These look exactly like the aluminum 40 rib wheels that were offered on lesabre and electra estate wagons for many years. However the wagons use the 5 x 5 bolt pattern. They were offered in the early 80's on lesabre sedans and coupes with the 5 x 4.75 bolt pattern. The smaller bolt pattern has a "lip" in the center hub opening, whereas the 5 x 5 opening is almost smooth (hardly any lip). see pics.
