I am running a 12A turbo out of a 83-85 japanese rx7. Does any one know the part number for the clutch, I know that the plate is a 215/24.5mm 22 teeth but there seems to be a few differnt part numbers for the kit ie. pressure plate? I intend to get an after market brass button and need to order the correct part. Greatly appreciated if anybody could help.
