Corvette six pack mechanical carb set up on a Chrysler six pack intake...anybody done it?

STOCK corvette tripower carbs are vacuum secondary too. (And not any cheaper than Mopar carbs). There were corvette carbs available on ebay, cheap, about two years ago, and someone here (wrong, it was on the B side) used them, but had to buy three side hung bowls, metering blocks, and a progressive linkage to make them work.
Mopar had an over-the-counter set of mechanical carbs.
(I'll see if I can find the vette carbs thread)
Found it, but it's on the fbbo side. "Tripower carbs for a 440 sixpack" Sonny's thread. Six pages worth of comment.
Edit: I was wrong about the "ebay", he was using holley factory refurbished vette carbs,.......that I don't think are available any more.
