Just noticed that under your Post number --- it's 273.
A question on the carb spacer. Does the perifery look as if it were cut out on a bandsaw? The one that I have does. All the holes look as if they were machined.
It is not overly rough. Not a clean polished edge, but not like it was cut on a band saw. Some kind of machining is evident.
According to everything I have read about your car, could Spehar have trimmed it down for weight reduction? He supposedly cut all the bolts flush to the nuts...that is pretty aggressive regarding weight shaving.
