I've found my stuff from various sources. For example I bought the triple SU intake off of SlantSixDan while over at .org; the carbs were sourced off of eBay and completely rebuilt by a company recommended by SSDan; the triple Weber intake off Australian eBay; the set of matching Webers from the eBay; the double roller timing set and windage tray/bolt kit I bought years ago thru Direct Connection. The Offy valve cover I bought through a group buy over at slantsix.org. Also bought a twin single Offy intake in the same group buy. The stuff is out there, you just keep an eye out for it and grab it when you can.
