The slotted plate/center pipe assy ain't avail new but they all (electronic ones/not points) interch ex the slot lengths are diff which you could live w that for now. If your pretty comfortable putting one together I'd get a cheap junk one for that piece but that wouldn't b as quick as buying a new one assuming a parts house had one avail on the shelf plus to do it right a new will still need to b taken apart & slot length/springs changed after you have finalized your initial but just to get you going buying a new one would b the fastest way to go esp one of the new MP Mallory built types w the externally adjustable curve
