Probably sounds petty but its little stuff like this this keeps you sitting at home instead of cruising your vintage Buick drives you crazy!!!! I bought a tune up kit for my 52 Super with the small straight 8 from the vintage Buick Parts place. The rotor button and the distributer cap wont fit correctly. Anyone else had this problem? The button is real tight and seems like its not going far enough down on the shaft and the groove which seems to be keeping the distributer cap from settling properly in its grooves!!! GGGGRRRRR! cant figure out why the most simple parts wont fit right. HELP Please.
