I am interested in putting the classic Buick Rally wheels on my '62 Special. All four corners will be changed to a 5x4.75 bolt circle. Does anyone have some 15" rally wheels that they can measure the back spacing on? I know the 15" wheels came in several different widths in that bolt pattern and am just looking to see which wheel is going to be tuck in the nicest on the car without purchasing them. Also if anyone has any of these wheels that they are willing to part with with out having the price as high as my first born child like many of these people on Ebay are asking, I would be interested in working out a deal. If so send me a PM. Thanks for looking. ~Dan
