Spacers? Which side do they go on? Hmm, now I'm curious if it'll work with an FB dizzy. The FD didn't even have a CAS. It might be a tight fit if it sticks up too high and gets in the way of the little 10mm nut/bolt which holds the dizzy to the front cover.

well we had to grind off a lot to fit with the fc cas. if you look real carefully you need a washer on one of the studs, the fd has a bracket or something that goes in there. you could always use the fc bracket, it's designed for a dizzy

I'd need to either oval one of the holes on an FB AC/PS pulley, or use an FC pulley even though the diameter is wrong. Or maybe I could relocate the PS pump to the top like it is on the aluminum brackets. Well at this point, I could probably get away with a gutted stock cast iron PS pump and one hole ovaled FB AC/PS pump on an FC main drive pulley. By gutted I mean trimmed here, shaved there since I won't be running AC. No need for that 15LBS+ ancient device. Hmm, maybe if I got an FC AC/PS bracket, I could figure out a way to relocate the PS pump? Hmm.

Almost forgot to mention that's the first time I've ever seen a dizzy on an FC that wasn't some sort of aftermarket setup. I mean that engine bay looks stock, other than the dizzy. Is that an early car?

I finally scanned some negatives. Here's a pic of a 4 port 13B on an engine stand with all four arms in use.
