i think speedway is carrying new granada spindles because they upgrade the wimpy mustang 2 stuff---also check jalopyjournal.com HAMB for a pictoral of the jag xj6 ifs/irs going onto a 1957 oldsmobile---on my hudson the wheel track was too narrow and i had to use wheel spacers to get my tires further apart---i think you might be surprised at how good it can work---and the XJ6 is a fairly easy crusher car to find if you are near a city anyway....bob
