One of the early type 3 FI dists is one of your best and most easily 
found options. I don't think there's anything wrong with the 009 
concept, it's more that the ones produced today are of poor quality. 
There's certainly nothing wrong with a mech advance distributor.

I doubt if the Webers have any pickoff point for a vacuum advance, 
and even if they did, you wouldn't know which vacuum can it matched 
up to. You're pretty much stuck with mech advance only. You might be 
able to use the 009, or use a FI dist and ignore the vac can. On OE 
setups that had dual carbs, only one carb and a vacuum pickoff for 
the dist.

An electronic ignition can be nice because it eliminates one 
maintenance chore, but they don't yet seem to actually be as reliable 
as one might hope. All in all, I haven't been tempted to invest in 
one yet. Despite what some may try to tell you, they produce no more 
engine power than a stock setup.
