Bill,

The Conical K&Ns fit from the box.  The part number is on Doug Jackson's web
site - if you need it hollar back at me.  Some have had to cut the rubber
spacers down, but I have been told that with "new" motor mounts, there should
be enough clearance with the brake booster.  I haven't put mine together yet,
though.  Hopefully by the end of summer.
