Earlybird, I just sent him a message asking about the brackets, so I will post when I hear back. I'll also have to look into the bell housings and mounts, since I have neither. My main concern here is now with the heads. 46 heads are all 98cc heads (except one), while stock 326s had 68cc, later ones with 72cc. I'm no expert here, but that is a significant reduction in CR.
