Folks,
I'm seriously looking at an Edelbrock 1902 carb to fit my "B" manifold; and, have talked with their technical support.  I was not given a lot of assurance that it would fit; neither was I assured they had the right throttle arm adapter selected as I tried to explain that the original (off a '57 mercury SW) carbutetor was a 1st-year Carter AFB.  They questioned whether the secondary manifold openings would accommodate their 1-11/16"  secondary throttle plates.  They also "thought" that the fuel inlet was convertible from right (passenger) to left (driver) side, but couldn't give me specifics; and, I've looked at their site for specifications and didn't find any details as to my questions their, either - frustrating!

And, they only have a 1/2" thick wood thermal spacer available. I thought that I should go with a 1" spacer - any suggestions?

Manifold is at another site some miles away right now - so...   ...I can't measure!  If anyone has dimensions of secondary openings (diameter and c-to-c spacing); and, mounting studs spacings dimensions c-to-c, I'd be most appreciative.

Thanks, JLB
