a day late...a dollar short. iwas actually hoping to find an intake for three or four carbs eventually, but suspect i may need to have it custom made. if anyone can point me in a good direction... many thanks. in the meantime, still looking for parts sources for clutches and just general part catalogues.second priorty will be headers and exhaust since my exhaust pipe and muffler have several leaks.
