WIW six pack air cleaner

I looked to see if I could find the carb mount spacing of the corvette tripower, but I couldn't find that info.
I have a edelbrock Sixpack for a 440 I could measure, but it's 200 miles away.
I suspect that the corvette and Mopar are the same, they both used vacuum secondary carbs.
Ford tripower spacing might be different, they used mechanical secondary carbs
